I got Doom 3 a couple of days ago, and I read on this site that to get it to work with Windows Vista, I need to update the latest drivers for my graphics card. I've tried doing it several times, even with admin settings, but I keep getting the same error message... "The Driver Being Installed Is not validated for This computer. Please obtain the proper driver from the computer manufacturers website". Okaay.... I double check I have the right driver. I do. Doesn't work.

Someone please help!
