I started iTunes on my new computer, authorized it, and poof! Every song and movie I've ever purchased was there. I downloaded most of the music and a few movies. Then I hooked up my iPhone 4 to the computer. I made sure not to sync it, because there was a lot of music on the iPhone from my old computer that was not on iCloud, and I didn't want to lose it. However, iCloud seemed to totally disappear. Every iCloud song and movie that I had access to just minutes before was gone. Only the downloaded music and movies remained. I lost a lot of stuff, and iCloud doesn't seem to exist anymore.
What happened? I would like access to all that iCloud stuff again. Why is it gone?
