Big Trouble with Colin McRae 2...PLEASE HELP!

[Dimitris]

I've tried every crack there is! See what happens :

- I've fully installed the game

- I've replaced CMR2.exe with the crack

I've started the game. Everything looked normal. I watched the intro, browsed the in game menus but, when I tried to start a race (any race in any country with any car) look what happened: whenever I reach a particular point on the road (a few seconds after I start the race), the game freezes and I need to reboot the PC!!! Please, anyone, help me! I'm desperate! Is this an internal piracy check or is my PC the problem?
