I updated my Digital Editions software yesterday and now when I download a book from my library (OverDrive) it opens fine on my computer, but when I try to transfer the book to my Nook I get the error message "Loan Token Not Found" . I have never had any problem transferring library books to my Nook before I updated the Digital Editions software.
I just purchased a Nook Glowlight 3, and I could NOT get it to communicate with Adobe Digital Editions (ADE). After many frustrating hours looking up and trying every troubleshooting tip I could find I FINALLY found this tip that worked; deauthorizing and reauthorizing my Mac laptop with Adobe Digital Editions (ADE). Maybe that will work in this case? Might be worth a try. Here's the exact forum response that finally worked for me:
"ADE often gets its authorization confused.
First return the library book ~ it is probably now authorized with the mixed-up id, and you might not be able to return it once your proper ID is registered.
Clear any old authorization using ctrl-shift-D to ADE (cmd-shift-D if on Mac).
Try again to authorize ADE with your Adobe ID.
Then you should be able to set the ID into the Nook as well; and borrow the book back again.
Good luck ~ what a rubbish implementation of DRM Adobe has produced...."
