Quake 3 - gives me an error about open gl. help?

[RSI]

I've seen it before, but I can't seem to remember how I fixed it. Q3 doesn't open, gives an error about Open GL. I still have my banshee. I use Win2K. What do I do to fix this? I installed a new driver and I thought it'd have installed everything I needed, but apparently not. Where can I get something like glsetup for win2k? I tried WickedGL but it still gives me the error.

ideas?
