Installation help

  • I played on Tera NA for about 2 months, recently having high pings and its been getting harder to find end game content parties because of different timezone; so i decided to try this server out.
    I would like to avoid downloading 40gb since i use satellite and its costly, is there anyway i can 'repair' or 'patch' my current Tera NA client to play here? I've tried letting the installer run for a few to let it create folders and then copying my 'Client' folder from NA Tera to the newly created folder but it didnt work.
    Its alright if there is no workaround, i'll just download the whole client.
