world war z trainer not turning on - World War Z

Been trying to activate the cheats when in offline mode but there not turning on the prepare light lights up when the game is on but when i click on it its doing nothing i have just installed the aftermath version for wwz and i have try'd turning them on when playing the new levels but no go even try'd it on the goty version levels aswell but they are now not activating.
Am using the latest EPIC version with no anti virus installed.

The game had an update. It's on the to-do list.
