when i try to play the game it says to me that i need the orginal disc to end the installation, when i try to play the single player i cant pass the part of chosing the dificulty, and i cant play on line
try using the full game+mod installer on http://cartographer.online
when installing using a disc or using a fishy copy of the game, a user error or a packaging error may prevent you from using certain functions
the installer made my the project cartographer team (tm) should prevent all these mishaps from happening
