Actually, the "one device" or "MAC only" ssues are no longer valid between MAC & PC (or so I was told - and we have three devices on our PC).
What I did was download the new version of iTunes to computer from the web. plug in my device and sign into my account when prompted. From there, I saw all my songs - bonus - i also saw all my husband's songs as they were on the Itunes that was downloaded (??) and I uploaded some of his purchased songs to my device.
I am not a computer guru. I just stumbled my way through this process and it worked - hope it works for you too!
Good luck!
