Lost Music

Hello, it sounds like a file association problem. When you say you've lost the tracks from CD, do you mean the tracks that you have ripped from a CD onto your PC?

If that's the case, then they should still be there!? Do the programs that you removed have anything to do with the way you either ripped or played your tracks?
I don't personally use iTunes or the iPod so I don't know a great deal, only that what you download must be played on apples' software/hardware.

But if I can find out what has happened to your other tracks it may help to point us in the right direction and solve the problem with your iPod.

Regards

Martin
