I bought an Ipod Touch after my Nano started skipping most of my tune list BUT after I got Touch from Amazon I learned I had to update my computer to XP. Tried to upgrade to XP and all hell broke loose on my computer. Had to wipe the hard drive and do a clean install. Everything is good EXCEPT when I went to "restore" my itunes purchases it only transfers them on to my Itunes library NOT my Itouch because I lack "authorization." How does one go about getting their previous Itunes purchases moved to a new Ipod? It seems weird I can get them on my computer but not on my Ipod. Help!
