you are lucky ^^
Trainer crash my game sometimes (i deactive) all options before end turn, but not so bad i just launch the game after the ctd and end the turn before activated the trainer and it's work
The trainer worked just fine for the first few hours, it crashed a few times ( I was experimenting). Then stopped working. Followed the updated instructions and I hear a "Trainer activated" at the menu screen and then in game nothing. The options are not working.
press F1 at main menu to activate trainer
if the game crashes there on activation, likely something is blocking the trainer.
the steam tool is no longer necessary. steam fixed that problem.
