So, my computer decided to do updates and I'd left Final Draft 8 up. The computer started to shut down and apply updates, but wouldn't move past the first one. I held down the power button and rebooted. Now my screenplay is 0kb. Any ideas on how to get it back?

By the by, it could be worse. I was making a manuscript into a screenplay, so I lost a few new scenes, but I can rewrite it. Still...I don't want the hassle.
