I need some Help With OpenGL

[babsie31]

Hi,
I have a NVidia GeForce2 GTS 32 Mb

I have had Medal of Honour before installed on here and i have played it. But now i have reinstalled it and it comes up saying "could not load OpenGL subsystem" now before anyone says to download a new driver, i have and it wont install all the way. Its startin to really annoy me ha ha ha. Does anyone have a clue as to what i can do? I am usin WinXP Pro.
