Remove from Bind Manager ALT from Toggle Aimbot and leave ALT Key inside Bind.

Remove ALT from Toggle Aimbot.
I am pretty sure because you have both Bind Manager and Aimbot key on the same key it will cause the Aimbot to disable itself until you press ALT again. This is most likely not what you want. So if you do it as i told you it should work fine. Your aimbot will start aiming on players when you press ALT.
