Medal of Honor problem

I just tried to start up MOHAA for the first time since I've upgraded from NT 5.0 to XP Pro.
This is the error I get when I try to start a game... any ideas?
I tried updating the driver... http://mirror.ati.com/support/produ...&prod=productsXPdriver&submit.x=13&submit.y=8
...but it didn't work.

 

What are you currently using for a video card driver? Windows XP default, or an older ATI driver? Default Windows drivers don't support OpenGL, as the note on that driver said, and MOH games are OpenGL games.

The way you phrased it I assume you've played it with that hardware, just not with WinXP Pro, yes?

What seemed to go wrong with the install of that ATI driver? Your best bet is to get that one to install properly.
