Activation Server error - code: Unable to authorize Nook

I am working on a Mac OSX 10.9.1.

I'm using ADE 2.0.

I am attempting to authorize my Nook.

The error I get is:

Activation Server error - code

Digital Editions encounter an error on the activation server.

I have uninstalled, reinstalled and restarted SEVERAL times.

Any ideas? Anyone? My frustration level at this point is at the intensity of a thousand suns.
