I purchased the game, but I can't get it started. I installed it, and everything seems normal until I go to campaings & missions to start a game. After loading, I get this notepad bug error: Exception core: 001 : error initialization program. I have installed the patch but no other mods. My system is more than capable, according to the in-game troubleshooting report.
Most likely the patch or mods is incorrectly installed. Try to begin game without a patch.
This error 001 informs that game does not find some necessary file for mission loading.
