Hi Gabby2000,
Two questions.
1. Is your Ipod/iPhone device Plugged in while your are doing this? If so, unplug it.
2. Turn OFF iCloud on your device while you are doing this you can turn it back on later, I had to do this and I apologize for not writing this in my original instructions.
If neither of these apply, then I am not sure what to tell you except you can run a system restore, find a restore point BEFORE all of this began it wont change your documents or files. And I don't think it will change your music, I hope you were able to recover that by the way.
To perform system restore, go to CONTROL PANEL\SYSTEM & MAINTENANCE\BACKUP & RESTORE CENTER once there choose "use system restore to fix problems and undo changes to windows" it is a blue hyperlink on the bottom not a button!! Then it will bring up a window, you will see a bunch of restore points, click on "choose restore points older than 5 days old" and try to find a restore point that you know will help you. Let me know if this works... Try the first part (answering the first 2 questions) before the system restore; which I have used many times.
