it works fine, but in chapter 2, where you have to extinguish the fire with the buckets, there is the water missing, when using the trainer. tried it without the trainer and it works fine. later in the game you have to extinguish a fire again (in one of the last chapters). there is the same problem. you need to get to that point without using the trainer. after "killing" the fire you can alt+tab and start the trainer.
