I have an Ipod that I just got and put on my moms laptop, but now I have a laptop so I put it on my own computer. My library will only show up if the iPod is plugged in and even then it is not my primary library. If I click on the library (at the top of the main Itunes page) no music comes up, to see my music I have to click on the music that is under the word "Devices". I'm so confused on what to do. PLEASE help and I can explain a little more if this sounds confusing!
Thank you :)

When you switched computers, the music was not transferred to the other computer. The best thing to do would be to load all of your music back onto your new computer via CD's and sync the iPod with it. If you purchased music from iTunes it should ask if you want to take purchased songs off the iPod and into your computer (and you do want that to happen).
