itunes won't accept that my computer is authorized to play some purchased tracks
like 15 of 45 songs i bought with a gift card wont play or download to an mp3 player. it says computer isn't authorized.
It is.
when i do the prompted apple id log in, there's no effect. it still says i'm not authorized to play songs. this happened before, but i don't remember how i solved it.
