Cannot transfer library book on my KOBO
I am using Adobe Digital Editions 4.5.11. I have downloaded books from our local library to my laptop. The computer is authorized as is my KOBO Aura One reader. I can read the borrowed books on my computer. When I look at 'My Books' on my Kobo, I see the books but the cover is black and when I try to open the book it states I am not authorized, DRM etc. I have gone back to the start a few times, deleted the books in question and cancelled the authorization on my laptop and reader, restarted from the initial download from the library and still no luck. I even re-initialized the kobo and re-installed ADE.
I don't know what else I can do. I have a MAC running under Catalina.
HELP please!!!!!
