--- Comment #15 from Anton Vorobyov phoenix@mail.ru 2010-08-15 09:54:33 --- Some additional notes:
Patch helped to launch game, but connection to server (according to comments above) seems to be broken, i'll check myself later. I'm not sure if exactly this commit broke it; do you want to open new issue or continue resolving in this one?
