Which error message get you when try to download? Do you used Windows or Macintosh?
I too would like to to uninstall and reinstall ADE. I use a Mac and Nook. My message is CE_COPY_NOT ALLOWED
Thanks for any help
Uninstall can you Digital Edition over Finder > Applications > Utilities > Adobe-Installer.
But it should not solved the issue. Check if have authorize his reader and the Digital Edition with the same Adobe ID.
