OpenGL Not Supported

I just formatted and installed Windows XP pro and Catalyst 4.4 drivers for my PC as 4.5 do not work for some unknown reason. I have the drivers installed and working properly but when I attempt to change the video mode in Counter-Strike 1.6 it says the video mode is not supported. I am sure it is because I see opengl32 in the System32 directory of my PC and it was working fine just a while ago. Any thoughts? My video card is an Asus Radeon 9600XT.

I have the same problem. Im running a NVIDIA GeForce 4 mx420 with windows XP. When i try and play CS 1.6 in openGL mode it says “the specified video mode is not supported.” Is there a way to fix this problem or is there nothing i can do?
