"GLW_StartOpenGL() - could not load OpenGL subsystem".
Googling for information, it says I need to update my video drivers. But, I have what I think is the latest video driver for both machines I've tried to play the game on.
Another suggestion was to come here.
One machine has an ATI Radeon 9600 Pro. I don't know the card on the other, but, the drivers are 'supposed' to be updated.
