Right well I appear to have some kind of a block on ANY game trainers I ever use, whether or not they are from cheathappens or whatever.
But I have noticed a certain pattern appear with cheathappens trainers. Each time I launch one, doesn't matter for which game it takes exactly 10 seconds to open up, something that only started to happen 2 days ago for no reason. And once they are open, I go ahead and open up Metro, activate it whilst hearing the activation sound, but the second I for example press the unlimited money key I suddenly get teleported into a wall, or an inaccessible location from which I cannot move at all. After reloading the last checkpoint it spawns me at the exact same inaccessible spot, and once again I cannot move. However after trying to go back to the main menu it simply crashes. All of this happens when I try to activate the trainer while already in game, but when I try to start it up before I launch the game it simply crashes the second the "Press any key to continue..." screen pops up just before the main menu.
Now I have noticed that ALL cheathappens trainers take 10 seconds to start up, which obviously indicates that it does not work. Tested your guys other trainers with Amnesia as well, with the same outcome only I dont get teleported anywhere, instead I hear the "Trainer activated" sound, press the keys I need yet nothing happens. It just doesn't work.
