I just downloaded Digital Editions so I can read proceedings from a conference. I followed the instructions but cannot add the
proceedings to ADE. The error message reads "Unable to add document xxx.epub. The document that you are attempting to
add already exists in the library" There is nothing in the library, can't add the "Getting started" . e-book - same message. I did
delete ADE and re-downloaded it. Is there anything else I can do? Any help would be appreciated. Thanks
