doom 3 won't launch

[rottenchopmeat]

hey all sorry to bother, but i recently downloaded doom 3 throught the pirate bay and i got the doom_3.toast file and the nocd crack. i got past the registration code but when i click on the icon, it pops up in dock, bounces and then it disappears!! i have no clue what i'm supposed to do from here. any suggestions? btw, i'm running on OS X 10.5.8 thanx

Buy the game. If you're lame enough to engage in illegal activity like this, at least have the sense not to post about it online.
