I got a brand new Nook Glowlight Plus and after borrowing a first book from my public library without problems, using Adobe Digital Editions on a Windows PC, I kept getting this error on every other book I borrowed. After trying different things and looking for a solution online unsuccessfully, I managed to fix the problem by doing an "Erase and Deregister Device" (from Settings -> Device Info) and registering again (NB login + DRM Settings).
I see a lot of questions about this kind of problems and not many solutions so I thought I would share what worked for me hoping it helps someone else.
Cheers.
