I have the Samsung Galaxy Tab 10.1 and have downloaded the Barnes and Noble Android app. It works very well, and all of my books cam across without a problem. One strange issue, I tried to import my books into the ebook app that came with the tablet. My magaxzines imported with no problem, but when I try the books I am asked for a user name and password. Itried my B&N user name and password, I tried my credidt card number as someon had suggested and nothing seem to work. Does anyone know what I need to enter toget the books to import?
