Downloaded book won't open on Nook Glowlight

I can open it in ADE to read on my computer but - although it shows up on my Nook, when i click on it, i am asked for Adobe ID and password.  I put that in and it still goes right back to asking for ID and PW.  I have verified Password word with Adobe Digital Editions (ADE), have deauthorized and reauthorized device, and still can't get beyond the request for ID and password
