Re-authorizing my computer to Sync my phone
I am trying to sync my phone and when I do iTunes tells me that my computer is no longer authorized and I have to go re-authorize it. But when I do it says my computer is already authorized. I then try to sync my phone again and the whole cycle repeats. I have even tried to deauthorize and authorize it again. What do I do?
iPhone 4S, iOS 7.0.4
