This computer is already associated with an Apple ID.
I keep getting this error
"This computer is already associated with an Apple ID. You can use iTunes Match on this computer with just one Apple ID every 90 days. You cannot associate this computer with a different Apple ID for 72 days."
I only have one Apple ID and no one else uses my MacBook Air. Any sollutions?
MacBook Air, Mac OS X (10.7.2)
