I recently installed a software package that took the liberty of "updating" my CD and DVD device drivers. Now, neither drive works. They are recognized by Windows XP Pro at startup, and Windows tries to install the "new hardware". However, it is unable to find drivers for either drive, even with a search of the Windows website. I've tried to find out exactly which files were replaced with no success. Short of reinstalling XP, I'm out of options. Any ideas??
