I just got the 4gig nano and i downloaded the newest version of itunes and i put in the ipod disk and downloaded it. I cannot find anything in itunes to export all my music onto the nano. Also, I've when i downloaded the ipod CD it only downloaded a bunch of extra stuff, no programs, like something to export music onto it. When I plug it in, nothing pops up on the desktop, or in itunes or anything. Please help!
