I have been able to download an Epub book from my library onto Digital Editions on my Windows 10 PC. I then drop and drag it to the Files folder on my NookGlow. When I go to open it on the Nook, I get the message "Book is not activated for current ADE user". My Nook and computer are both activated to the same ADE ID. Barnes and Noble say its an Adobe issue. Any help is appreciated!
