Crash on startup...[Problem solved]

[Your Computer]

Okay, now I can at least boot it again,(As I meantioned in the readme file of that little prerelease, it didn't even boot anymore) but it doesnt fix the problem I had in the first place; it still crashes when I try to enter the first map.

Right, but i figured since the issue is now isolated to a map that you'd be able to solve it. Unfortunately, the dialog box that the game showed when trying to load the map didn't provide much information, but you should be able to check your hpl.log to get a more descriptive message.
