Ok .... I bought and downloaded FPSC, downloaded the 1.05 RC2 patch (and yes, I do have the latest DirectX)
However, when I built and played the game (I built all the demo levels, just to test out build game) it glitched.... The enemies only occasionally appeared, I could see the Win zone as a very thin white rectangle, and all the doors and windows were compacted into strange shapes (see screeny), and a lot of the textures were missing or wrong........
Help would be "awesomeness", thanks.
E.D.
EDIT: Added screeny, look closely at the window......
And yes.... my pc does run it......
