When I download a book from the Overdrive Library in the Adobe epub format to my Nook HD+ , I get a dialog box asking for a userid and password when I try to read it. It will not take my Adobe password and userID, it tells me one of the two are incorrect. I have the nook HD+ authorized with Overdrive with the same password and userid as my laptop computer. What is wrong and how can i fix this problem? Do I need to deauthorize both the Laptop and Nook and startover?
