Music can't be copied on to iPod, not authorized
After having some problems I restored my iPod. I now get this message when manually loading music from the library: "(song)" was not copied to the iPod "My iPod" because you are not authorized for it on this computer". I checked, and this Mac is one of two authorized. Any way to fix this?
iPod nano, Mac OS X (10.6.8), 5th generation
