function keys don't activate certain cheats

Whenever I try to activate certain cheats for Dying Light, I only get the typical error sound. On some, they work.

Make sure you using current trainer and read notice below regarding cheats since you forgot to mention which certain cheats doesn't activate?

You may try running with Administrator rights. Sometimes even everything works, we have to right click the executables and use the "Run as Administrator". There it may be also wrong version of game and using wrong trainer version. It matters that. Do as the above user said.
