Downloaded ADE 3.0 authorized computer and device, device shows up fine, (Kobo Wifi) drag and drop library files (.pdf and .epub) , seem to load onto the Kobo fine. When you look at the Kobo drive when connected by USB it shows the files have been added to the Digital Editions folder so all seems well. But when you disconnect the Kobo and turn it on to read on the reader they do not show up at all, it only shows purchased books from Kobo Store. Please help. Thanks!
