this is very perplexing. where can i get an openGL driver for my sis 5597/5598? i am having no luck with this stuff...
the screen blinks like the game is about to begin but then my regular screen comes back and i have this jabble about open GL...
thank you in advance...

oh i forgot to mention that on my other computer that has xp, the game started but there were millions of colors and it just looked horrible and the cursor was huge and i couldnt see anything. its a sony vaio and doesnt even have the option to go to 640x480 which is what the manual says you should set it to manually when you manually run it from the start menu.
i cant get this working on either computer.
