Another (Steam) Demo crash-on-launch

[Urkle]

Did you try having steam re-download the demo? (by deleting the local cache or even by verifying local files.)

You can do that by right/control clicking on the game in and choosing properties. Then from the "Local Files" tab pick verify integrity of game cache or delete local game content.

My first thought is it didn't download correctly to your system and it is somehow corrupted. I'll investigate further here.
