Help with a hack.

I've been searching around for some simple hacks to use in combat arms. I've attempted to inject a few times with Perx and after injecting I clicked the insert button but the key functions for hacks like Nightmare and etc did not appear. My laptop also requires me to hold "fn" for certain functions but that and clicking insert without it did not work. I must be doing something wrong or nexons 2012 version of combat arms is immune to the available hacks. I've been searching for any hack. I'm not seeking anything big. I'm also new to this site. Any help?

Ah thank you to everyone. I did however, bought a new keyboard and that seemed to have fixed my problem.

I'd say most hacks are detected. I've done hours of searching through these forums. Found many hacks, read many threads. Examples, Nightmare CANA 1.6, Xipher, Flameswor, many more (etc). all detected within a couple minutes of gameplay. Many people would respond to a thread saying "It works great for them." or someone would link them to a hack that "works" but as the rest, detected within a couple minutes of gameplay. I've also tried using Byte Cipher to scramble the .dll and renamed them. But most hacks were posted during the past couple of years and nexon has been under maintenance recently, so I'm not really sure what to conclude. The most logical thing to do would be to wait for new updates and releases.

Use Xiphers hack, or Biohumans, or even the hotkey hack by fatal. One of them is guranteed to work.
