Just checking that you know about resources such as Project Gutenberg http://www.gutenberg.org/
for a huge number of DRM free eBooks (mostly older classics that are out of copyright).
You can read them more conveniently on the open source Clibre software than on ADE. http://calibre-ebook.com/
It might be worth trying Adobe Live Chat to see if they can help http://www.adobe.com/support/chat/ivrchat.html
but I wouldn't hold out too much hope.
Good luck.
