I already tried refreshing SDK content, uninstalling and reinstalling SDK, installing SDK on newly installed Steam, I even tried reinstalling Windows... Nothing helped. When I debug it with MS Visual Studio, I get: "Unhandled exception at 0x0b10b9ec in shadercompile.exe: 0xC0000005: Access violation reading location 0x00000000." I'm not having problems with any other program. I'm using Windows XP Professional SP2 on computer with Pentium4 3.0Ghz CPU, Asus P5GPL motherboard, 1GB RAM, GeForce7600GT graphic card.
