How do you loopkill on roblox using cheat engine

This is what I have:

To loopkill you need a Cheat Engine.
1.With a Roblox place running,open the cheat engine and find the Roblox Place(The glowing button at the top left hand corner).
2.Press Memory view.
3.Right click on any of the green numbers you see.
4.Press "Make page writable".
5.Press Search(beside File).
6.Select Find Memory.
7.Type in torso.
8.The first code you see should have torso as the name.
9.Now double-click on any of the green numbers on the torso's code.
10.Overwrite it with any number you like(Make sure you remember the original number!)
Then everyone in the server should start dying.
To stop it,just change the number you messed up back to the original one.

The problem is, the game just shuts down. no loopkilling.
