This computer is no longer Authorized to play purchased items that are on the iPhone
I just moved all my files from my old PowerBook Pro to my new PowerBook Pro which came with Lion pre-installed. Everything has worked fine except that when I try to sync my iPhone to my Power Book, I get a popup box saying that "This computer is no longer authorized to play purchased items that are on the iPhone. Would you like to authorize the computer for items purchased from the iTunes Store?" It also warns me that if I do not authorize this computer, 132 items will be removed from the iPhone. When I tell it to authorize, it then tells me that the computer is already authorized, and then I get the same message again. I have tried deauthorizing my new computer, then try syncing again. I tell it to authorize, it tells me that authorization was successful. Then I get the same popup and message telling me that this computer is no longer authorized. I have deauthorized the old computer.
Would appreciate any suggestions you might have.
Thank you,
