v; Have you tried opening Word? Because I know sometimes when that happens to me, if I try to either restart the computer or open Word, it'll pop up saying that a document was closed before it got saved or anything, and wondering if you want to save it or not.
That's not as bad as not saving them to an email and then your computer gets wipped out and you are seven chapters into the story. There is always a million ways to write a chapter........or at least three...........or five. I don't know.
