I recently got the error message "not an ADEPT EPUB" when trying to decrypt the epub file.
The problem is that the epub archive no longer contains the file "META-INF/rights.xml", which normally contains the encrypted book key. It seems Adobe has changed their encryption mechanism :-(

Since Adobe Digital Edition 1.7.1 can open and decrypt my book (even when I'm offline), the question is, where is the book key? If we knew this, we could fix the script. I looked into "Application Data\Adobe\Digital Editions", but couldn't find anything.
If anybody knows more, I'd like to hear it :-)
