Error message, opengl problem with q3a mod urban terror.

I’ve been trying to play urban terror and have been getting the following error message…

Quake3 has caused an error in NVOPENGL.DLL and must be shut down, please restart your computer.

I run winME, have geforce2, and have run urban terror basically nonstop for over a year, with no problems like this. I DID download some modeling programs the other day, GTKRadiant or something like that, i was thinking of trying to maybe do some mapping, i’d never done anything related to mapping before. I mucked around with the gtkradiant thing, and after that, is when my problems with running urban terror started.

I dl the latest nvidia drivers for winME from nvidia’s site, and when i try and run it, i get “that is not a valid win32 application”…

Any help?

Any help? Oh, and i CAN run vanilla quake3 online with seemingly no problems. Its just urban terror…
