I've used digital editions for over a year without any problems. Now, each time I attempt to move downloaded books to my e-reader, I'm told to authorize the computer. After authorizing, I continue with the download and the books show on my reader. When I attempt to open the books, they show as INVALID FORMAT. Should I un-install digital and then re-install, or is there a secret to making it work properly?
Moving this discussion to the Adobe Digital Editions forum.
