Can anyone help please? I cleared my old library in iTunes before buying another i podclassic. I have now added my music to the new library and it says it's syncing but then it comes up with a message telling me that I can't have 2 libraries. It asks me if I want to delete my music from this ipod and sync this new library. When I click yes, it still shows that I have no music in my i pod. So I'm stuck. Can anyone advise please?
