My itunes account is authorized on 5 computers and I want to put it on another. Recently, my hard drive crashed and all my backup is on a separate hard drive. I purchased a new hard drive for the computer. Since I had to reauthorize iTunes on my computer’s new hard drive, that leads me to believe that it is still authorized on the old computer’s files. Is there any way to access this itunes to deauthorize it, or and remote way to deauthorize devices from my account? I’m using Mac 10.5 by the way.
