I have also tried removing and reinstalling the ATI latest drivers (I have an ATI Radeon HD 4870 on Windows 7). I have also tried disabling AI from the CCC. I bought the game through steam but I get the same problem running the programme directly.   
If there's anything else I've missed please let me know. Thanks.
