PM-M Can't Load CLUT

I just removed my old video card and uninstalled it's drivers. I then installed a nVIDIA GeForce 7900 card and it's drivers. I now am getting a message when I boot the computer saying that the CLUT cannot be loaded. I did not have this problem before. Any ideas what may be causing this problem? Thanks in advance for the help.

If you changed video drivers you would need to recalibrate your display.

I realize that, but when I do, it appears I would not be able to use it because of the problem I mentioned. I'll try recalibrating tonight and see if the problem goes away.

Unfortunately, I was correct. PM-M will not run. When invoked, it gives the message, "Your display adapter does not support color lookup tables". I realize this is probably not a PM-M-caused problem, but I'd appreciate any hints as to what the problem may be. Thanks.

This message indicates a problem with the video drivers not supporting color lookup tables for some reason - possibly because you are not running as an Administrator? Other than looking for more recent drivers to download I'm not sure what else to try.

Similar message occurs in QuickGamma. I fixed it on XP by going to Display Properties/Settings/Advanced/Troubleshoot, and moving the Hardware Acceleration slider from None to Full.
