Does the game crash after you do a specific action? If so, you should head to the bug reports forum and describe the action, along with a copy of your srb2win.RPT file if you have one.
I think what happened was, I turned on OpenGL mode and I didn't have the 3d models that the game can run. But without those models the game wont run. Or maybe it's my ram idk. And how do I share my copy of my srb2win.prt?
