Our sincerest apologies!
In a recent effort to resolve a bug in the code... another bug snuck in!
The crashes you may have experienced occur in NEW game installs, as an important start-up file has "gone missing in action"! Anyone who had been playing the game previously should be unaffected.
This has now been fixed with a PATCH to the installation on Steam.
If you are experiencing a crash on launch please update your install so you see BoC Demo v 0.101.171 (or higher). This release is now live on Steam, so you should get the update (sometimes you have to log out and back in to force Steam to make an immediate update).
Once again, our apologies for the inadvertent launch problem!
