I tried sideloading a DRM protected book through Adobe Digital Editions to the Edge. The book loads into a folder called Digital Editions, but the Nook reader does not see it. Copying to the Nook My Documents folder does not work. I can see the book, but it does not open. The Nook reader just closes, no message -just poof - it's closed. Apparently the side load trick for DRM books only works on the actual Nook device, because the books go directly from Adobe Digital Editions to the Nook my Documents folder. In order to make this work, Adobe Digital Editions authorized my Nook. Since the edge is preloaded with Adobe ID the edge does not authorize in the same way. B&N staff was totally unhelpful when I first bought my Nook, tech supports answer to how to read books purchased elsewhere (Sony bookstore) on the Nook was "we don't support Sony DRM". It took me a couple of hours of browsing to find the answer, so unless the Nook community figures it out I'm stuck.
