Just updated to lasted Digital Editions version as I just bought an e-book. That book downloaded fine but all my older books were gone (Changed to a new laptop a while ago). I then tried to 'add to library' and selected any of the already purchased book's .acsm files. This brings up a dialog box 'fulfilling' the book - the bars go all green while downloading - and then it just hangs there forever. I have to kill the digital editions again using task manager. Platform: Windows 10. Please help me retrieve my 5 digital books that I have purchased.
