Kobo Aura H2O can't open borrowed books from Library

I have ADE 4.  Computer and eReader are both authorized.  When I open the library book on my computer under the Kobo section, it opens fine, but when I try to open it on the eReader, I get a message that says:  "Oops! This document is protected by Adobe DRM and is not currently authorized for use with your Adobe ID..."  Thoughts?
