Alright, so I'm up to my 5 computers when it comes to authorization of iTunes. The only problem is that I forgot to deauthorize a few and now I can't. That really wasn't a problem until randomly iTunes decided the MacBook I have right now isn't one of those 5. So the question is.. how do or better yet.. can I deauthorize computers that I no longer have access too.. like a computer thats dead for example?
