My tech teacher at school has a rollercoaster tycoon 3 at his class loaded on a computer. He used a cracked CD because the students were stealing it, and now when he or the students attempt to start the game it gives this error message:

Runtime Error!

Program: C:\Program Files\Atari\RollerCoaster Tycoon 3\RCT3.exe

R6025
- Pure Virtual Function Call

Someone got an idea whats wrong?

Apparently it's a programming error.
