Unable to sign into Adobe on Nook Tablet

Hello!  I recently downloaded an ebook from my Adobe Digital Editions on my PC to my Nook Tablet.  I then attempted to sign into the Adobe account on my Nook so that I could open the book and it said that my Adobe ID or password were incorrect.  So, I logged onto the Adobe site on my computer and changed the password and confirmed that the change took, then I tried to log in on my Nook and again I received a message that my ID or password were incorrect.  I double-checked the ID username and have been entering it correctly and I've attempted to reenter the password, but I continue to get the same error message.  Does anyone have any suggestions?  I appreciate the assistance!

Thank you!
