Got a new computer and downloaded digital editions and can't copy from library to my Nook. Any advice? I never had this on my old computer and Digital Editions looked different. Thank you!

Hi everyone!

My old computer died so I've been trying to add new programs to my new one.  I always borrow books from the library to read on my Nook.  I can still borrow them and open them in Adobe Digital Editions, but I can't copy them to the Nook.

If anyone knows how to fix this I'd really appreciate the help.  I never had this issue before even the very first time I started using the library and digital editions.

Thank you!
