Following a recent up-date of my Nook Color, I received an error message stating "No permission to copy documents here." I was attempting to transfer downloaded epub library books from my computer to the Nook. Barnes & Noble personnel attempted to install Overdrive. During that installation process, Adobe Digital Editions failed to recognize my password. A new password was requested. However, ADE failed to recognize my e-mail address and would not complete the installation of Overdrive. How do I resolve this problem?
