Trying to copy downloaded ebook to my nook, get message that I don't have permission to copy. Never had this problem before. Any suggestions?

I'm glad to see I haven't completely lost my mind.  Thanks for responding and letting me know.  Hopefully we'll get help!

Same problem ??? Where to get an answer???

This is a new error, as I just downloaded a book from the library and get the same error message.  It says no permission to copy the book....  I have always copied books over to my nook from the library.  Hopefully someone has an answer soon.
