ok so usually my ipod works fine when i plug it into itunes but recently when i opened itunes this thing popped up and it was an ipod updater or something so i updated it and then i updated itunes and now my ipod is only uploading SOME songs onto my ipod and it took off a bunch of videos that i have and it doesn't let me take videos off that i want to take off. it took off ones that i wanted to stay on there, i don't know to do or why the hell it's doing this!!
