Dartmaster01 said: Pixel Shader 2.0 is part of directx which is part of windows. Every game needs specific directx files to work properly which is why most games have a directx download upon installation. It seems like these files may be missing or corrupted. You may want to verify the game files in steam and there is a directx installer in the game's files (CS can point you in that direction) for you to re-install.The other thing that jumped out is after checking the specs of your cpu/gpu, the i5-520m only supports up to directx 10. You said the game was running on this machine before though, so this isn't likely the problem unless they changed system requirements (your original question). I had this game running on a XP machine in the beginning so I know it was possible, just don't know if it still is.Just some ideas, let me know if CS can't fix it and I'll see what I can do
Dartmaster01 said: One more thing, you may want to try to run the game's exe. in compatibility mode for windows Vista and/or XP service pack 3. Make sure you have administrator rights for this or it won't work. Hope this helps, let me know how it turns out.
