First time using the trainer, on the latest patch #13, using only the XP add, trainer is activated, but doesn't seem to be add XP while in game.
Edit: Definitely not working even though it says Activated. Just tried it with mask patterns too.

Unfortunately there was a update of the game so the trainer works with some of the features but not with all anymore. At least that is my experience. For example. The mask features tend to crash the game. No damage doe not work for high jumps anymore and with ammo cheats your ammo is still depleating but if you hit the keys it will fill up again.
So there my be an update comming to fix it. I guess there are working on it as the update just happened so give them a bit time
