Same happened to me. When I try to log in there is always popping up "invalid account data". I even downloaded game again. Changing password doesn't work.
I have wrote a ticket to support, alright. They answered 2 days later and asked me for my e-mail, character name and server. So now I am gonna wait 2 more days?...
PS. BTW I can't buy TC... what will you do with this guys?
Can you call it even as contact? ~
