I tried to move DRM ebooks onto my new ereader by dragging them across in windows explorer. (I've always done this before). It seems that is no longer an option with DRM, or not an option with these particular books. My solution (after a whole day of fussing, searching, reading, giving up to rest and later going back to the problem, finding hints and ideas all over the place and putting them all together) was to delete the ebooks off the ereader via windows explorer, open ADE on the computer, click on the ebook file on the computer that I wanted so it would open in ADE, click the library link in ADE, ADE asked if I wanted to add the ebook to the library, I said yes, then find the ebook again in the library list in ADE being careful to choose the copy with 'new' on it, then drag it onto my ereader device list in ADE. It still had an entry for the ebook on the device (memory, I could write a song about that) so I chose to replace the ebook on the device (skip was default) and now I can read the ebooks I want on the ereader.
Yeah, intuitive easy to use software.
