Programs will only run once.

As for the nature of the crash report, event viewer says this:
Faulting application name: ThiefGame.exe, version: 1.0.0.0, time stamp: 0x5307767e

I must add that this is when the game crashes, typically when trying to make a problem happen it doesn't happen as normal I can't get it to do the thing it normally does (with no error report) at this moment, but will update when I can
