Some purchased on same album require authorization, but not working
I purchase an album from the iTunes store that had 19 tracks on it. 16 of them show as "Purchased AAC audio file" and play fine in iTunes. The other 3 show as "AAC audio file" and won't play. Instead I get a popup that says "This computer is not authorized to play. . . would you like to authorize it." When I go ahead and do that it tells me that the computer is already authorized and it doesn't change anything. I still get the same pop-up when I try to play it. How do I get the other 3 to play and why does it do that?
