FearLess Cheat Engine

Hey, can you do a tutorial for how to get items from the cheat engine? I've searched everywhere for a tutorial and i can't find one. I'm really dumb and need someone to walk me through it because it's way too difficult for me to do it. And no matter what I've tried it doesn't work for me. Thank you ...

So when i choose the nutaku application and try clicking enable nothing happens, is there some sort of issue happening because the game is newer. Can you help me with this issue?

Does the the engine update by itself or do i have to reinstall it?
