Random crashing?

[ethanfgm]

After anywhere from a couple of minutes to almost an hour, my game randomly crashes. Nothing appears to trigger it, and there are no error messages of any kind. I only have the 20 in-game day demo, and the crashing happened both in 0.45b and 0.46. I tried downloading java6 u30 but nothing changed. My laptop doesn't have much of a problem running it, so it's not that. Anyone have any idea what is going on here?

The game closes and go back to the main menu when the game reachs the day 20 (in-game time, not real time).
