How to Inject

Hi friends. Hello friends, I have stooped this hack "http://www.mpgh.net/forum/175-crossfire_hacks/55553-cf_esp_aimbot_speedhack_updated.html" and it me does not work. The first thing that I do is to open the Injector. Later, I load the DLL, later I open Crossfire, give him " START GAME " and select the process rapidly "crossfire.exe" and give him "INJECT" he(she) says to me " Inject Suces Full " I give Him "OK" and in the item(game) it me does not work at all. Since it is injected?

THANK YOU
