We have taken all the solutions we could find on our forums, and merged them into this one thread. If you know a fix on an issue then please contact one of the Board staff and we will add it.
    Let me give you an overview of the structure:

    First of all make sure to check the following in all cases!
    • Run the tera-launcher.exe with admin rights
    • Check your firewall, anti-virus or other software if it blocks the access for TERA to the internet or at all. This normally involves the files "TERA.exe", "TL.exe" and "Tera-launcher.exe". If you use any kind of anti-malware software or other security software please check those as well!
    • Do not modify your game client in any way, if you do so, the patch process can be broken and you won't be able to play/update the game properly. Also a modification of the game client can lead to a permanent account block/ban.
    • Try to use the repair function of the launcher.
    • Last resort: Uninstall TERA and remove all remaining TERA files from your system and download the game again through the current launcher/setup file.
  • General issues and possible solutions

    TERA requires administrative privileges to run properly

    Follow these steps to do this :

    Note: You must be logged in to an Administrator account!

    — Find the TL.exe file.
    - Navigate to C: Drive -> Program Files -> TERA -> Client.
    - Find and right-click on "TL.exe" and select "Properties".
    - Select the "Compatibility" tab.
    - Checkmark the box that says "Run this program as Administrator".
    - Click "Apply" and then click "Okay".

    — Find the TERA.exe file.
    - Navigate to C: Drive -> Program Files -> TERA -> Client -> Binaries.
    - Find and right-click on "TERA.exe" and select "Properties".
    - Select the "Compatibility" tab.
    - Checkmark the box that says "Run this program as Administrator".
    - Click "Apply" and then click "Okay".

    Note: These locations correspond to the default installation location.

    Your TERA client should now have adequate permissions to run properly.

    TERA may require Windows XP Service Pack 3 or higher

    Some functionality problems were reported when running on Windows XP Service Pack 2 or older, it is advisable to upgrade to Service Pack 3 or higher. Windows Update is the easiest way to do this.

    I encounter graphical artifacts in-game and/or TERA crashes when I modify any video/graphic settings

    Update your video card drivers.

    To do this, go to your video card manufacturer's website, find the Drivers/Support section. Download the latest version, install the package, restart your computer and run TERA again.

    AMD Radeon - Latest Catalyst Drivers
    nVidia - Latest GeForce Drivers

    Note: If your manufacturer has provided other links, please visit those instead.

    You can't login into the browser nor in the client

    Usually this problem is linked to your computer-clock not being correctly synchronized. To synchronize your clock with a timeserver, do the following:
    • Click on Control Panel
    • Navigate to Time and Dates
    • Go into the “Internet time” slider
    • Choose “change settings”
    • Check “on synchronize with the internet”
    • Now click on “update now”

    Please do also check the forums for server maintenances or similar.

    Ping problems or Delays

    Often it helps if you change some things in the Registry. That will work for every game then.
    But you are responsible by yourself if you change things into you Registry.
    • press Start and type regedit in
    • then click on HKEY_LOCAL_MACHINE and then go to System and CurrentControlSet
    • now you select services and search for Tcpip, then you click on Parameters and after this on Interfaces

    • now you search for your local network IP for example
    • now check the directory for TcpAckFrequency and TCPNoDelay
    • if you don't have this files, then right-click->New->D-Word-Value(32Bit)

    • now select TcpAckFrequency, right-click and Select modify and type in 1 at the Value
    • the same for TCPNoDelay

    • now you need to go to HKEY_LOCAL_MACHINE->SOFTWARE->Microsoft->MSMQ->Parameters
    • and search for TCPNoDelay, if this is not there, then just create it with a Right-click and a click on DWORD
    • now another right-click on TCPNoDelay and change the value to 1

    • restart your PC

    Stuck Character

    If you have a character that got stuck in game then you can report your issue here: Stuck Characters?

    I tried to register an account on the website and I got the following error "Failed to generate fraud prevention signature"

    Generally, you can resolve this problem by trying the registration with another browser (Internet Explorer, Firefox, Chrome etc...).

    Also, you can try to delete cache & cookies of your internet browser to solve the problem.

  • Issues with the Game and possible solutions

    XmlLite.dll could not be found

    You are missing the XmlLite.dll file, which can be added rather easily:
    • First you have to download this dll-file.
    • Copy it into you “C:/Windows/System32/”
    • Restart the game

    Error: 011336b1 Game Execution Failure

    This error can be solved by installing a security update for “Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package ATL”. An actual version can be downloaded here!

    "Fatal Error Exception" and/or TERA client crashes without notice

    There are three known instances which can cause these errors :
    • You let your computer go idle after logging in to the client.
      In this case, you can simply restart the client and you won't encounter the error again.
    • Your anti-virus or firewall is denying or restricting TERA.
      Turn off your anti-virus completely and restart the game. It is advisable to add TERA.exe and TL.exe to your anti-virus' exception list, so you can have your firewalls active without blocking TERA's access and functionality.
    • TERA requires administrative access to run properly.
      Take a look at the solution under 1. General Problems & Questions

    "Launching" Issues

    Play button does not work

    • Be sure to check the general steps listed at the top of this thread.
    • Check your time settings of your system. Go to "change time and date settings" and check if you time settings of your local system are set correctly.
    • Deactivate the P2P setting in the launcher of TERA. Now restart the launcher and click on the repair option.

    Error: 000a:0000 insufficient memory – the game won’t start when hitting the “Play”-button

    As some files haven’t been downloaded completely, or haven’t been installed correctly, a memory-error occurs.

    Follow this to repair your client:
    • Start your launcher and click on “Launcher Settings”, then turn “P2P sharing” OFF.
    • Now close the launcher, and restart it after a couple of seconds.
    • Then repeat the above, but this time, turn “P2P sharing” ON.
    • Now click on “Click here to Begin Repair” and wait till this finished.

    Your play-button should work fine now.

    TERA launcher doesn’t start – the games doesn’t launch when pushing “Play”

    • Delete the file "gl.version"
    • Start "TERA-Launcher.exe"
    • Now the launcher updates itself
    • After patching, one is able to use the play button

    or :

    There seems to be a problem with a folder in your TERA-directory. You’ll have to reinstall the game into your TERA directory.

    Get black screen after clicking on play button but i can hear sounds

    To fix that, you need to modify the file S1Option.ini in \TERA\Client\S1Game\Config
    In that file you will find a line called "SCREENMODE=0". Change the "0" into a "1" and try again.

    Downloading Issues

    Run Tera launcher using /window command

    Some times the patch progress seems stuck, but most fo the times it's just the animation thats frozen. If you run the launcher into window mode then you will be able to see if it's actually stuck or what file(s) that is causing the problems.
    1. Open up your command prompt (CMD). The easiest way to find ti is to use your computers "search" or "run" function
    2. Now, when you have your CMD up, start by typing "cd\" (without the qoutation marks).
    3. Now type in "cd Program Files (x86)\TERA" and hit enter. (Or wherever you saved the folder)
    4. Finally, type "tera-launcher.exe /window" and hit enter.


    Right mouse button on Tera shortcut > chose Properties > in box Target at the end of the line put space and write /window > push OK button > run launcher.
    Example: C:\Games\TERA\TERA-Launcher.exe /window

    The launcher should now start with an extra window where you can see the progress of the patch even if it may seem stuck on the launcher. In case of an error you will be able to see that file thats causing the issue. If ur still experiencing issues then try deleting the .version file and repatch.

    Issues with patch process and download of the game client through the launcher including the message "No download error detected"

    • Download the following file (.exe) in order to fix the issue (Download).
    • Execute this file on your system.
    • Now re-run the TERA-launcher.exe in your installation folder of TERA.
    • The launcher will now correctly download and/or patch the game again.

    In case this does not help, you can go for a fresh install of TERA:

    1. Use the uninstall function of the TERA client.
    2. Remove possible remaining folders/files from the previous installation of TERA.
    3. Download the latest version of the TERA launcher setup here.
    4. Execute this file and the launcher should now correctly start the download and patch process again.
    5. Please make sure, that the TERA-launcher.exe and TERA.exe files are not blocked by your firewall or anti-virus software.


    If your launcher only downloaded a small file, but won't start the main download, you'll have to use this fix.

    Source delivers incorrect files – no secure source found – error with the HTTP-client-transfer – Error while downloading the manifest-file – sudden speed-decrease while downloading

    Two different solutions to this problems:
    • Start the TERA-Launcher
    • Go to “Launcher Settings”
    • Turn “P2P sharing” OFF

    • Click “Start” – “Control Panel”
    • Now on “Network and sharing center”
    • On the left select “Change adapter settings”
    • Now select your adapter (WLAN or LAN depending how you are connected to your router) and click on “Properties”
    • Uncheck “Internet protocol 6 (TCP/IPv6)”
    • Then select “Internet protocol 4 (TCP/IPv4)” and click on “Properties”
    • Choose “Use the following DNS server addresses”
    • Now enter “” above, “” below
    • Click on “ok” and restart your PC.

    Launcher update problem

    • The launcher downloads an update to the folder TERA-Launcher.exe.update folder
    • It then closes the launcher so it can overwrite files in the main game folder with the TERA-Launcher.exe.update folder's files.
    • This is where it goes wrong; it tries to overwrite the files but for some reason the files are in use and can't overwrite them, so the update never completes, although it deletes the TERA-Launcher.exe file from the main folder.

    Having done this now countless times I feel, this has worked every time.
    • Copy/Cut the files from the TERA-Launcher.exe.update folder to the main game folder.
    • Delete the TERA-Launcher.exe.update folder.
    • Rerun the launcher.

    When trying to do this it is important to note that this might yield an error message saying that the files is already in use, just keep trying for a minute or two and it should sort it self out.
