I use a steam version of it.Coul i have some help?
My Game simply closes when im trying to launch a mission,
I'm having the same problem, the trainer launches fine and activates at the main menu but crashes during the loading for a mission. I also have the steam version.
I didn't really pay attention and downloaed the GOG version because it was on top and had the issue that you two are facing - activated in the menu but crashed when loading the mission.
You need to download the 2. version as this one is for the steam version of the game.
I'm using steam and the trainer works as described.
