If you have successfully transfered the file from your computer to the Nook here is what to expect. Turn the Nook off like you are finished reading (not a full shut down) leave it along for a while. The Nook while in the "sleep" mode will detect the file and execute the update. When you "wake" the Nook, in the notice bar at the bottom of the screen you will notice a small green "n" open the notice. It should announce the successful update. Clear the notice and go back to your book. If this does not happen I would suggest deleting the zip file from your computer and attempt the entire process again. Let us know how it works out.
