I've got a problem with my iTunes - recently all the new albums I've added (whether purchased from iTunes or imported from a CD) won't play, instead an exclamation mark appears next to them when I click them saying file cannot be located. I have my iTunes backed up on an external hard drive and all the older mp3s still play fine, but nothing from the last couple of months does. I know I could add them again but I really don't want to lose all my play counts! Is there a way round this and does anyone know why it's happened? Many thanks for any help!
