I purchased the upgrade a while back but it disappeared from my iPod and computer. I complained to Apple and they were great about it and told me I can download it again for free. I was to told simply "check for purchases" and then log in and it would download. However, nothing happened. I did e-mail them back but I don't think they are going to say anything that will help me. Has anyone gone through the same thing or know what to do to get the upgrade?
