I downloaded ADE on to my MAC and activated it under my email address and password. Unfortunately my Nook is set up using my husband's email and password so it will not recognize the book that I have downloaded with ADE. Is there any way to change the user account on ADE?
In order to fix the problem please follow the steps as given below.
Now connect your Nook to your computer and open Digital Editions.
It will ask you to authorize here you need to enter your ID.
I hope this will help you!!!
