sins crash - auto save games?

Hi, I'm using vista and was wondering where sins places its autosave games? The game crashed, and sins doesn't give auto-saves as an option to load nor do I know where it places these files. That might be a good option to have in another update, if sins closes unexpectedly have the most recent auto-save as a loading option. It's been a four hour game so far, and I don't want to lose it.

Thanks!
