i need some help with mechwarrior 4 black knight
 

I was wondering if you’d come by someone who has encountered a problem with MW4X.EXE or any suggestions on how to fix it.
The problem is that whenever I try to play the Final Countdown level in Campaigns, it only works for about 30 seconds then the game crashes.
You can take a look at what the error looks like with the attached screen shots.
