I tried to play Doom 3, I can access the main menu and Dooms 1 and 2, but whenever I try to start a new campaign, the game crashes and I get this error:

Any way to fix this?

Have you updated your ATI/AMD Radeon drivers?

If Updating drivers doesn't work try RBDOOM 3 BFG.

Managed to solve the problem by downloading an older atloglxx.dll driver and copying it to the Doom 3 folder.
