Have you tried shutting your Nook down completely and restarting? This will typically clean up this issue.

Has anyone found a solution for this? I'm having the same issue and nothing has worked.
I deleted the epub files from Windows Explorer on my PC, but the thumbnails persist in my library. However, they do nothing when tapped. I've searched the entire MyNook drive for *.epub and *.jpg with no results.
