I have iTunes match and it's the best service I have ever used. I can't even imagine not having it. I've run into a problem, though. My wife and I are currently on vacation and right before we left she logged into her user id on my macbook and synced up her iTunes for the trip with her own id. Now when I try and use iTunes match on my own login it tells me this computer is already associated with another ID and I will have to wait 90 days. I can't access my music during vacation and it's really becoming a bummer. I sent a ticket into apple about my problem and 2 days later they replied back with instructions on how to turn on iTunes match, like I was an idiot who didn't know how to click the turn on iTunes match button, but the problem is that when I try to turn it on it tells me my Macbook is associated with another ID and I will have to wait 90 days. I'm sure it will be another 2 days before they reply back to me. Does anyone know how I can get iTunes match working on my computer again and not have to wait 3 months?
