I can open the ADE box. It will show my Nook device and books that are borrowed, but it will not show the bookshelves for ADE so that I cannot transfer a book from the library to ADE, then copy it to Nook. This has never happened before and I've had ADE for a decade or so. What's up with it today? (I can download both 3.0 and 4.5, neither one will show borrowed books or let me download additional books to ADE. 'Sup? Thanks! Stay safe!!
