Desperate.... Ati radeon 8500 & OpenGL Need help please

Hi ! I’ve just installed my new graphic card ATI Radeon 8500 (275/275) and it works perfectly with Direct3d (8428points at 3d mark) so the card is correctly installed.
I need to install OpenGL and it doesn’t work !!! it explains me that it doens’t find any compatible video adapter… GRRR it is compatible !!

Any Ideas ?

What operating system are you running? WinXP?

Make sure you download and install the latest drivers from Ati,
