Nook Glowlight Issue: "Error opening book. This book has been returned."

[#1]

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. -_-

I am having the same issue after having many books loaded successfully in the past, as recent as a few months ago.  Has anyone figured out what the problem is yet?

I was able to get the solution to this issue from my local library and it worked for me:

These errors typically occur if there's a problem with your NOOK's authorization. You should be able to fix the issue by resetting the Adobe credentials on your NOOK using a computer.

Note: These steps don't work for the NOOK GlowLight Plus, which is authorized differently than other NOOKs.

Note: We recommend always using the latest version of Adobe Digital Editions (ADE).

1. Open Adobe Digital Editions (ADE).
2. Make sure your computer is authorized with an Adobe ID or an OverDrive account.
   In ADE, go to Help > Authorization Information.
   
   Note: If this option is grayed out, please authorize your computer before continuing.
   
   
   
   The authorization window will open and show you what credentials you're currently using for your computer.
   
   
3. Close ADE and wait a few moments.
4. Reset the ADE folder on your NOOK.
• Connect your NOOK to your computer.
• Go to [My] Computer and open the drive associated with your device (likely named Device (X:), where X is the drive letter).
• Locate the .adobe-digital-editions folder and delete it.
5. Open ADE, then try transferring the ebook again. You may need to disconnect and reconnect your NOOK for it to appear in ADE.
6. After the transfer, disconnect your NOOK. You should now be able to read the ebook on your device.
