I just bought the game today and I haven't actually played a game yet because when I attempt to start a game it crashes with the pa.exe window. I've tried looking at all the other forums and tried all the solutions and none of them have worked.
Most likely it's caused by outdated drivers: Code: Card name: AMD Radeon HD 6800 Series Driver Date/Size: 4/20/2011 02:07:48, 795648 bytes You need to download and install latest drivers from AMD website: http://support.amd.com/en-us/download/desktop?os=Windows 7 - 64
