How can I authorize my Samsung Galaxy Tab 4 Nook to accept my ADE e-books?

I have transferred my ADE e-books onto my new Samsung Galaxy Tab 4 Nook (7").  However, when I try to open them, they ask for authorization (email address and password).  How can I authorize my device so it will recognize information and open my books? ADE doesn't see the Samsung Nook when I plug it into my computer, and the Samsung doesn't understand when I enter my information.  I'm running ADE version 2.0.67532.  Thanks for the help.
