the game was working perfectly until level 7 :the forest of ruin so i'm not sure if my video card is the problem but it says D3DERR_INVALIDCALL:
it happens when i start mission 7 then enter the 2nd room past the giant red orb giver
Try going to Start > Run and type in 'dxdiag'. Or hold the Windows key near the left Alt button and press R, then type that in. Then make sure everything is enabled and run the tests.
See if anything is wrong. If not, try reinstalling DirectX and Direct3D. Also, have you tried the level on both DX9 and DX10 versions of the game?
