1. Did all that. Still getting message:
This book has been returned. Loan not on record
This is nonsense. ADE showed it in the borrowed list and I could open it and read it in ADE. But after I transfer it to NOOK, even though it shows up in the Digital Editions folder (well over a megabyte file), it wont let me read it. Instead it presents the above error dialog.
2. Tried deleting from ADE (OverDrive says no books borrowed. 4 available copies). Checked out and completed delivery to ADE. Readable in ADE. Plugged in NOOK. Dragged ADE image to NOOK in ADE file list. Before I could eject the NOOK got the error message from ADE:
