Transfer of epub book from library to my Nook Glowlight

[cfauks]

I have not tried to transfer an epub book from the library to my Nook in months.  I used to have no problem.  Now I am unable to do it!  I get two error messages:  "user not activated" - so I fixed that ( I think!) and then when I tried to transfer again, a "CE_copy not allowed" type of message.  Several questions:  is the glowlight supported?  do I use Adobe Digital Editions to do this (like I used to) or is it now Overdrive?  when I download the book from the library, it shows up as an Overdrive file...do I need to "open with ADE" instead?  That seemed to work and the epub showed up in my ADE library, but I wasn't able to transfer it to my Nook.  Any suggestions out there!  Help!

You are Digital Edition and your Reader authorize with the same Adobe ID?

This is the message I get when trying to download EPUB book to Nook Glowlight:

Error getting License. License Server Communication Problem:

E_ACT_NOT_READY

Support from Adobe couldn't help. Suggested I de-authorize then re-authorize. Got same error message.

Suggested reinstalling Digital Editions. I did and still get same error message.

I have a Mac with OS 10.11.4
