hi heres what i think just check your computer for viruses you probly have the diabl virus eatcing away at your registry and that could cause anything the computer thinks is malitious code will not be loaded correctly try that it should work for you update your virus definitions or go to the nortin anti virus website and download the fix for the diablo virus and it will clean everything up ok hope that helps^^;;
just get version 3 and the script is cut down to this,
MouseClick("left")
MouseClick("left")
this is to just double click the mouse but you can add in the rest just put mouse move,mousedown,mouseup,mouseclick thats all and you will have a more stable script.
