Any way to open book that was not exported, but the library location moved instead?

I thought I backed up/exported my book I was working on, but when I try to import it into the latest version of Booksmart, I get an error message that says it wasn't exported. I am guessing I relocated the library for it instead. When I go add the book files to an already existing Booksmart Data folder, the book is not in the list of books to open when I launch Booksmart. Is there any way I can get this book to open again. I also tried putting the booksmart data folder into another computer's same folder that hasn't updated to the latest version and I still get the same message. HELP!!!!!
