The game runs fine but when you first start it there is a message that says that a service pack is needed, it seems to think Win 7 is Vista pre service pack 1. LOL. :D
It works fine for me - in single player but I download my games via STEAM so that they are always patched, - do you have all the latest patches and what settings are you using in game?
When I try and play COD either 4 or World at War its fine for single player but when I try and join multi-player I get kicked off the servers by Punkbuster for having an 'invalid O/S'. Please can we have Punkbuster get updated! ------ Windows 7, 64bit build 7000 GeForce GTX280 x2 SLI EVGA...
