I just got a nook, and I am having the same problem.
Did you ever get yours to work?
Yes....when you open up your nook it should have adobe digital editions on the device....if not you need to call the nook line and have them reconfigure. It took me a month to get someone on the nook line to help me but someone finally did and it works like a charm. It was very frustrating and I thought it was my old mac but it had nothing to do with it...good luck.
hope it was clear......when you plug in your nook to the computer and open
it, that's where you should see an icon for ADE and if it's not there nook
has to put it on which they can do over the phone.
I hadn't seen that anywhere.
I have not tried to call in yet - time hasn't allowed that one.
Will be working on that later this week.
We'll see how far I get!
