I have win 8 too and they work but they always get blocked the first time i try to run a new one. I get a blue bar on the screen saying windows blocked it. There's a link on there (i think it's more info but i can't remember). If you click it there will be a run anyway box. this fixes it with windows and then the trainers will work, assuming your antivirus isn't blocking it after that. Mine does that too so i have to put an exception in for them.
