I think your problem is that you're not using it in the Toribash Client. Follow these steps derp.
1. Place the script into C
Games\Toribash-X.X\data\script (replace X.X into Toribash Version)
2.Open Toribash
3.Press Esc
4.Click Setup > Utils > Scripts
5. Select the script (in this case MoveMemory.lua)
6. Click load.
If you did this right, it should put red text on the bottom left corner of your screen explaining what to do.
