Ok, did what you said, started the game first, started the trainer, pressed F1 and it said trainer activated, and that's the only thing red. Are the rest suppose to be red? Nothing else is red. Just F1. Yes, I downloaded the lasted trainer that's up. EDIT: I got Mortal Kombat X set up on my daughter's computer and logged into my steam account on hers. For some reason the trainer works on hers (my game is on her computer and mine). I press any of the F keys on mine and it doesn't say anything is activated except when I press F1 and it says it's activated. On her computer, any of the F keys it says it's activated. I can't figure out why it works on my daughter's computer and not mine. Any help would be greatly appreciated. I do thank you so much for this trainer quickly after MKX's release.
