So I got past all of the authentication issues on Ubuntu 12.04 amd64, and now I'm running into an issue where the game freezes when I hit the "Start Game" button, following character creation. No error messages or any output what so ever. I tried logging into general chat before hand, but that made no difference. I haven't read about this issue anywhere else, and was wondering if anyone has any ideas? I'm using an AMD video card btw.
