STUNTS problems...
 

This is a problem about PLAYING the game. HOW DO I DISABLE THE CARS SECURITY SYSTEM? It tells me to fasten my seatbelt then it tells me I forgot to disable the car's security first...

There are quite a few executable files that can be run. You're starting the game with the wrone one obviusly :)
I don't remember which one it is exactly, but check for all *.com and *.exe files and try playing until you get the right one :)

The right file is stunt.com, stuntS.com is the original and is not cracked like the first one. -Eagle of Fire
