I have successfully downloaded an epub book to the Adobe Digital Editions program on my HP computer, using Windows 7 Pro operating system. I have been unable to transfer the book to my Nook (Samsung). The Computer shows that the Nook has been loaded into the computer, but it does not appear automatically within the DE Library as it is suppose to. This is a new problem as both the computer and the Nook are new devises. Please tell me what I am doing wrong and how to transfer the book to my Nook.
