замените ваш skvCreateRequestObject на пример ниже

function skvCreateRequestObject(){
	try {
		return new ActiveXObject("Msxml2.XMLHTTP");
	} catch (e) {
		try {
			return new ActiveXObject("Microsoft.XMLHTTP");
		} catch (ee) {}	
       }
	if (typeof XMLHttpRequest!='undefined') {
		return new XMLHttpRequest();
	}
}
