registering device

[markr35749099]

After resetting/rebooting my Mac Book and reinstalling ADE, im getting the error message:

"You can only authorize the computer with / using an Adobe-id that has not been used for the authorization of a computer or mobile device. Try again"

So... somewhere in some Adobe database somebody checked a box that I already registered a device to my account. Which is true, it is this mac book that I just rebooted, and now I can't get to my ebooks anymore because I cannot register this device again. HELP
