Hello All, I tried using my CD-ROM Drive, which would not read any of my cd's. I looked in the Device manager, where I found the following error message under CD-ROM drive: Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52) I've tried to enter "bcdedit.exe -set TESTSIGNING ON" in the command prompt, but my cd drive still does not work. What else can I do? Does having ITunes create that problem, as I have heard that before?
