Hello, I have found some of my old mp3 cds I created on this computer. I am going through them and trying to find out what is on all of them. For some reason my comp isn't recognizing any of the mp3 format ones. Any clues what's up with it? it makes a noise like it's reading it and then won't do anything. It even spit one back out at me.
