I am trying to download a library book to Adobe Digital Editions so that I can download to my Kobo. I keep getting the following error message:

Never had this problem before - today's the first time.

Any ideas? Thanks!

thank you. I ended up uninstalling ADE and then reinstalling an earlier version. It's working for now.
