I have searched for this error with no luck, so I am hopeful someone here can help. I'm trying to export a book from CS5.5 to EPUB, but I keept getting this error: "Style source document in book is missing." This is not true, the style source document is most definitely not missing. I have tried restarting numerous times and changing the style source document to another chapter, but nothing works.
If it makes a difference, this book was built in CS3 and converted to 5.5.
