Run the game from batch file or command prompt with -log appended.

wolfram.exe -log

This will create a log file;
C:\Games\Wolfram\system\Volatile3D II.log

Check the error at the end of the log file.

As per your suggestions,i checked game log after crashing. At the end of log it is saying that "Engine_Error: R_BindGLSLShader: tried to bind NULL program". I can't understand! what is this? please help me to fix problem. I also tried with patch v1.1, still same crashing problem!
