ADE "you can only authorize this computer with an Adobe ID that hasn't been previously used to authorize any other computer or mobile devices"

[elinb98470930]

Hi, my problem is that when I try to authorize my new MacBook with my Adobe ID when logging in on Adobe Digital Edition it says:

"you can only authorize this computer with an Adobe ID that hasn't been previously used to authorize any other computer or mobile devices"

Although right above it says: "Authorizing your computer enables you to: Easily transfer Adobe DRM protected items between multiple computers and mobile devices" etc. which I interpreted that, I should be able to use this ID on multiple computers, in my case my new MacBook and also my stationary computer. So... why do I receive this message when I try to authorize? Could it be because I'm authorized on my old computer? I don't have access to that computer anymore so how do I erase that authorization?

Plz help

Kind regards Elin
