I am not sure Jordy but I think that Apple itunes, may have noted your new ip address and is probably blocking any that you downloaded via itunes itself. Any that you added to your library from a cd will probably play. Apple probably identifies your pc as a different device since the move, so you may need to do a log in or set up your machine as a different device. I am sure that you can have a maximum of 5 devices on your account and that includes ipods, ipads, and laptops.
