Do I need to start over?

Okay, so I'm using ZC211b184 and I think my file crashed. I was making my quest and then I increased my map count from ten to eleven so that I could create a new dungeon dmap but then when I placed a single tile, a bunch of weird tiles covered the screen and then zQ just closed itself on me. Now whenever I open zQ and try to load the DoR-Tileset.qst file zQ closes. Do I have to repeat all the progress I made? Or is there anyway to get around this?

I could take a look at it if you post a link here, but chances of recovery are quite slim. You did make backups, right?

If you're going to do a lot of work on a beta, for God's sake, at least use a recent beta...
