Every time I try to start a campaign, tutorial, or multiplayer I get a loading screen and then an error message telling me the program has stopped working. I more than exceed the recommended requirements and my graphics driver is up to date, anyone got any ideas about what might be wrong? I got the game off Steam, in case that makes a difference.
My System:
Intel E8500 3.14Gz
GA-EP35-DS3L
MSI Radeon 4850
2x WD Caviar 640GB HD
4GB Corsair Twin2X DDR2 800
Antec P182
ASUS VW222U 22" LCD
Windows Vista Home Premium x64 SP1 [LEFT]
