is anyone there who can me help ?

Try this for a test, take the original code as shown here and replace it with 

function PauseNew(secs, milli){   position = "core.js";   whatfunc = "PauseNew()";   var duration;   duration = (secs * 1000) + milli;   WScript.Sleep(duration);}

This code here:

function PauseNew(secs, milli){   position = "core.js";   whatfunc = "PauseNew()";   WScript.Sleep(1000);}

Then run your WPI

i have tested, WPI does not start, script error in many scripts, after the change
