I'm having the same problem, where the error occurs the moment I open it. There's not a lot you can do to fix it in that case, you might have to start over. I know that's unfortunate, depending on how far along you were.
What I'd recommend doing is starting over, but saving often. For each successful save, make a copy of it somewhere else. That way, if this happens again, you have a backup you can work with, and it might be easier to figure out what went wrong.
