Yes!! I was having trouble getting my library books to load to my Nook and the help at the library said to be sure my Adobe ID matched my Nook ID. Well, I hade changed my Adobe ID and couldn't erase it....I thought. I couldn't get Adobe help after waiting on the 800 number twice for an hour each, i gave up. But i contacted the library help and they told me what to do:
Resetting your Computer's Adobe authorization
1. Open Adobe Digital Editions (ADE) if it's not already open.
2. Press Ctrl + Shift + D (Command + Shift +D on a Mac) on your keyboard.
3. Select Erase Authorization, then OK.
4. Try authorizing your computer again by going to Help > Authorize computer.
I did this and was able to re-authorize ADE with the matching Adobe ID and I got my books to transfer. The ones I took from the library with the non-matching ID, wouldn't transfer, but any new books I took out did transfer without a problem.
