Before I screw up my new Ipad..... I hadn't backed up my ipod to my laptop, which I was going to be using with the ipad. So I plugged in the Ipod i set up the computer to be authorized, and it asked if I wanted to have the ipod synced in itunes--I said yes. Two seconds later--there was nothing in the itunes library on the computer and nothing on the ipod. All 2500 songs are missing. So what do i do now?? I think the tunes are in the istore on my desktop computer upstairs. What happens if iplug in the ipod on the other computer?? I want to take the laptop to the Apple Store, the Ipod to the Apple store, and the ipad for their set up. So I need your help.....I haven't plugged in the ipad yet.
