Windows 2000/OpenGL & UT problem

I recently "upgraded" (har har) from Windows 98SE to Windows 2000 Pro (I don't recommend it). But, now I cannot get OpenGL to work with UT. Directx 8.0a works okay with it, but I much prefer OpenGL. Detailed textures have never worked with DirectX for me but works great with OpenGL.
I have a GeForce 2mx with the latest NVIDIA drivers for Win2000 installed. When I put the game into OpenGL rendering I get software mode instead. (Atleast I hope it is software mode cuz it is dithered, non-mip mapped, slow junk)

Any help would be appreciated.

I did get the most recent opengl driver listed on the epic support site. I've been using that driver for some time now and worked fine under Win98se. But, Win2000 sorta boofed the whole thing.
