There was a problem in Word when I numbered the document. I had 2 page 5s (Chapter 1). But only in Word. In Open Office, it was fine. I made it as correct as I could in Word then opened it in OO and put the final touches on it there.
CreateSpace still wasn't happy when I considered it perfect as a .doc. I converted the exact same document to a PDF and then CS became Happy Happy Happy.
