I have apparently lost a file that contains something to the affect of "rndll32.exe" as I get a message that so states. I have also tried to copy files to a CD however the drive doesn't seem to recognize the media is in the drive. The same is true for the DVD as well. About the same time, if I download .pdf files, the computer downloads and then tells me the file can't be found. Any pointers? Thanks Tractor
