I did sign a disclaimer, so I'm not complaining that the computer was wiped. Maybe I didn't understand the nature of my backup. I thought I had a full backup. I use time machine and an external hard drive, and back up every hour. I was confident that everything would be restored. I was able to restore everything from the backup drive and didn't notice right away that there was nothing in my iTunes. The thing that's odd about it is I know that my iTunes account exists because I can get everything that was in iTunes on my phone. I was just wondering whether anyone else has encountered this. My next step is to call tech support.
