Nook Glowlight Issue: "Error opening book. This book has been returned."
I'm having an issue reading library books on my Nook Glowlight 3. I bought the Nook last year and have had ADE 4.5.10 the whole time. I've read tons of library books and haven't had any issues. All of a sudden I am unable to open the epub files on my nook because they are saying they're returned. I can open the files in ADE on my computer and in the Libby Library app so I know they haven't been returned accidentally. The only information I can find on this error is from 2015 so I'm hesitant to download an earlier version of ADE since the 4.5 version has been working for over a year without any problems. The issue is occuring for ebooks I've had on hold and ebooks I've borrowed immediately (I've tested a few). Anyone have some newer information on how to deal with this error? Or contact information for Adobe DE? I tried calling the regular Adobe Customer Service number and they had no idea what DE even is. -_-
