❗ after inject nothing happen

im using the pyinject that i download from this site...i use the pds farm dll and no spread and no recoil dll that i download from this site....it said it was approved....i open up the injector then i start NWZlauncher... ava is loading to the point where it saids, type in ur user and pass.....in the injector i open up NWZlauncher exe and open up my dll.... when the game start there is a notepad that save on my desktop and said success have fun with your hack...i was so happy and thought that finally this injector works!!!!!!! i press up but nothing happens for the no recoil....for the farming i went into the room and did everything but as i check there is nothign happens also.... NeXT thing i try was load the injector to ava exe instead of nwzlauncher and still nothing happens....the question i have is that for injectors to work, do you need to injector before the game rigth?? next thing i also try was that cheat engine.... i try everything like farming, to add guns.... still nothing work.....when i did the gun adder, i use that scan 2343 n the steps....i finally got the 876 type in the value and the gun pop up when u click buy but when i click buy it fail like in people's video, i can see the money of how much it worth and stuff but i see nothing.....Lehsyrus if u can help me that would be so nice
