Hello and welcome to the community. :slight_smile:

  1. Have you pressed the Play button in the top-right of the trainer to activate it?

  2. What happens when you press they hotkey? For example, nothing? Or does the cheat flip on then off?

  3. Where did you get the game from?

  1. I have press the play button
  2. it does nothing
    3 from steam legit
