Prior to today, ADE was working fine with my Nook Glowlight. Today, it downloads the library books fine, and my Nook shows on the desktop, but once I turn the Nook on, ADE closes abruptly. I have deleted and reinstalled ADE, unauthorized and reauthorized, taken the new book out of the ADE library and added another; same problem. I also tried it on another computer with the same result. I am able to purchase and download books from B&N with no problem.
