[HELP]Urgent help for programming hack

Hi guys, i'm a beginner then i ask here :D
S4League when you open my hack closes immediately
The hack is done in AutoIt and this is the code:

Code:

#cs ----------------------------------------------------------------------------

 AutoIt Version: 3.3.10.2
 Author:         Papera

 Script Function:
	Template AutoIt script.

#ce ----------------------------------------------------------------------------

; Script Start - Add your code below here
#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <Nomadmemory.au3>
$GUI1 = GUICreate("Papera's Trainer", 400, 200)
$Label = GUICtrlCreateLabel("Papera :=)", 350, 170)
$Checkbox1 = GUICtrlCreateCheckbox("Inf SP", 15, 50)
$Button1 = GUICtrlCreateButton("START", 180, 140)
GUISetState(@SW_SHOW)

While 1
   $nMsg = GUIGetMsg()
	  Switch $nMsg
	  Case $GUI_EVENT_CLOSE
Exit
	  Case $Button1
		 _hack()
EndSwitch
WEnd

Func _hack()
   GUISetState(@SW_HIDE)
   MsgBox(0,"Attezione!","Divertitevi :=)")
   $WAIT = ProcessWait("S4Client.exe")
   MsgBox(0,"Attenzione!","In attesa di S4Client.exe")
   $PID = ProcessExists("S4Client.exe")
   MsgBox(0,"Attenzione!","Processo esistente")
   Sleep(500)
   _MemoryWrite(0x0052F0C5,_MemoryOpen(ProcessWait("S4Client.exe")),"0","long")
Exit
EndFunc

a more request, in "(_MemoryWrite(0x0052F0C5,_MemoryOpen(ProcessWait( "S4Client.exe")),
"0","long") instead of the zero I put the value hacked?
Thanks and sorry for my bad english :D
