I understand that but I'm logged into my apple id. When I first got the message I was updating iTunes match. I have to be logged in to update iTunes match meaning no one logged into iTunes while I was away. I only have two devices authorized my macbook air and my iphone. I can still use it on my iphone

Did you ever get a fix?
I'm in the same boat. I only have one Apple ID. I signed up for iTunes match on my work computer. Came home, tried to add my home computer (which has more music), and boom this error.
Now I also can't download any music I purchased on my iPhone to my home computer.
Google searches help not at all. Man, this is incredibly frustrating.

Did anyone ever find a solution? I too have only one Apple ID. The same one for years that my wife and I use exclusively. But this past week I started getting the message "This computer is already associated with an Apple ID". As a result I can't download any music to my iMac that I've purchased on my iPhone or iPad.
Apple email support says that somebody had to have physically gained access to my iMac for this to happen. To say that freaks my wife and I out- we live alone- is an understatement. And it simply isn't true.
I am personally convinced that this is some sort of error somewhere in the Apple ID/iCloud/iTunes servers. But I need a way to elevate this somehow beyond the iTunes support gatekeepers who basically only say "no, it's your fault."

I agree, this is probably an error on the server-side. If you have one nearby I would suggest a visit to the nearest Genius bar.

I'm another one-account user receiving the same error. Apple email support has so far been useless. I think there is a legal case here if they sell us iTunes Match and deny us access to the very service they sold us. This is very frustrating...

Oddly enough, I just realized the date it thinks I switched Apple IDs is the date I made my last purchase... with the exact same Apple ID....
