When I download a book to a usb file, it will not open. Is there something else that I need to do?
The computer that you would like to read the book on has to have Adobe Digital Editions installed and you must have authorized it with your Adobe ID. Once that has been done, all you need to do is double-click on the file that is on your USB and it should automatically open in Adobe Digital Editions. You can also right click on the file and choose to open with Adobe Digital Editions.
