wanted

Hey guys.
I have big problems with the BO2 Codehook.
My game is always crashing if i leave a game.
If i use sniper i don't get any shot with aim fov 20 or higher and the silent aim also brings nothing and if the enemy is about 10-20 meters away catches the aimbot on the foot to attact.
Can someone help me / give me good sniper settings?
Thanks.
