I was using Adobe Digital Editions 3.0 for my old Nook. It broke so got new Nook GlowLight Plus. Someone told me to uninstall old Adobe Digital Editions 3.0 and install New Adobe Editions 4.5 which I did. When I bring books into my computer they show in the rt side of the screen but I don't see the Nook bar on the left column thus can't drag the book over to my nook. What am I doing wrong?
