Authorizing new computer for nook

Question

Hi everyone,I've just spent the last four hours trying to figure this out. I used to use my nook on my dell laptop, but I recently purchased a mac. When I tried to move books from the library to the nook, I got an error that said the book could not be copied.  I want to transfer it so that I am downloading and transferring files from the public library to my mac laptop, but I can't authorize this computer. I am getting an error that says the following:"You can only authorize this computer with an Adobe ID that hasn't been previously used to authorize any other computer or mobile device. Please try again"I tried deauthorizing my old computer with the nook connected, but nothing seems to work. Should I just make a new adobe ID? But then I'm concerned it won't be connected to my library account. Please help! I miss reading from my nook

Sometimes ADE gets its registration/activation confused and in a semi-authorized state.

Uninstalling and reinstalling does not help.

Unfortunately, it often then gives misleading error messages about what is wrong.

A common incorrect message informs you that the ID is already in use on another computer and cannot be reused.

This can often be resolved by completely removing any authorization using ctrl-shift-D to the Library screen on ADE (cmd-shift-D if on Mac).

Restart ADE, and then reauthorize with your (old) Adobe ID.

In extreme cases on the mac, the following extra step has helped some people. Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash. If you are using 10.7, see Access hidden user library files | Mac OS 10.7 Lion. http://forums.adobe.com/thread/1265248?tstart=0
