Per trainer notes:
As of version 1.07.02 the developers have added an anticheat to the game.
To be able to use the trainer you must launch the game with our launcher.
Make sure the game is closed, then launch the trainer and click on 'Launch game
without anticheat'. If you want to restore the original launcher click on 'Restore
launcher' instead or verify your game cache in steam.
Our launcher is does NOT modify any game file. It launches the game without anticheat
as the original launcher would do. It cannot be used to cheat online and we never support
online cheating in any form.

Is this the way you are using it?
Then you have to manually browse to the game's installation folder where the start.exe is located.
