I'm so sorry to leave you guys without answer for many days :| But the good news are that the problem was solved when i deleted the game and downloaded it again. I guess some part of the tutorial level was missing and it couldn't play because of that. But now it plays very well, i just got sucked in...

I'm pretty sure it's not problem with dx or hardware. I have latest 64bit drivers. But I can play singleplayer and multiplayer normally, but the TUTORIAL level is bugging. How am i supposed to play if i don't know how to play... Anyway if you really want my dxdiag, here it is ------------------ Syst...

I can launch the game normally, everything works when i go to the first tutorial level, i can move around, but when i press scape to start the game, it counts down from 3 to 0, and crashes. Bought the game via steam. Is that the problem or is it with my computer? Specs: Vista Ultimate 64bit 4gb DDR2...
