iTunes computer authorization
Whenever I try to play a song on iTunes, it tells me my computer is not authorized to play that song. Dialogue boxes appear asking for my iTunes/Apple ID and password. I enter them correctly, and they're accepted, but that does not work.
I've seen advice to delete the song and re-download it. OK. But it looks like I'll have to do that separately for every song in my iTunes library. And that would be, frankly, bullshit.
Any suggestions?
