I recently bought a C.D. and wanted to upload it to iTunes and put it on my iPod, but it would not load. I thought, "Oh, it must have a security thing." So I tried it in a C.D. player. It worked. I tried once more with the computer, and it failed. The driver shows up. But there is no C.D. I even tried another C.D. to see if it was just the one I had bought, but it wasn't. Any ideas?
