[Fossilbooks]

I bought my Kobo a couple of days ago in Toronto, ON Canada.
I have downloaded an epub file from my public library. When I connect Kobo by USB and choose "manage library", I get the kobo reader icon in the navigation pane of ADE. But when I try to drag the book to Koboereader icon on ADE I get the message "No permission to copy the document here."
What am I doing wrong? I have an Adobe ID, and have authorized my computer. Do I have to do something to authorize my Kobo? The literature says once authorized, I can copy to 5 different computers or ereaders.
(Your forum answered another problem of mine: getting rid of a book that had already been returned, and that ADE kept finding. Good stuff. Thanks.)
