I installed the K-Lite Codec Pack for windows 7 x64 and it removed some 'spoilt' codecs. I don't remember installing any codecs so i don't know how it got there

i can play the intro movie using windows media player but when i start the game i still can't get past the intro cinematics.
Hmmm, i updated my DirectX, PhysX, Visual C++, Drivers and all but it's still not working.
I'm running Windows 7 x64
ATI Radeon 5770
Gigabyte QuadCore i7-860 @ 2.93 GHz
4Gb Ram
Any ideas?
Thanks
