Sniper Elite 4 trainers doesn't work

Hello everyone,

I’ve never used Infinity before and Sniper Elite 4 is the only game I have. At Infinity interface, all the buttons are frozen. What I’m doing wrong?

Have to hit the play button for it to work

Nothing happened…and I’m confirm I linked the diretor correctly

What exactly happens when you click play? There should be a checkmark next to it after a few seconds

Ok, I got it, I have to open the game first, alt+tab, than click play and the buttons turn on. Thank you guys!
