Hi Jen, For some unknown reason, this morning I had exactly the same thing happen to a book I was proofing! Luckily, I had saved an older copy of the book and when I opened it, success! Though I had to reproof about 50 pages, that was better than redoing the entire book! By chance, do you have another copy of your book? Sure do hope so and perhaps you'll have as good luck with it as I did! Susan
