markerclusterer_compiled.js throwing error for Markers

We are using Google Maps API V3 Markers to show markers in the google map
when we search using location.
Below is the code we are using to call Google api.
script.Append("<script type=\"text/javascript\" language=\"javascript\"
src=\"http://maps.google.com/maps/api/js?v=3&sensor=false\"></script>" +
Environment.NewLine + Environment.NewLine);
script.Append("<script type=\"text/javascript\" language=\"javascript\"

src=\"http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/src/markerclusterer_compiled.js\"></script>"
+ Environment.NewLine + Environment.NewLine);
script.Append("<script language=\"javascript\" type=\"text/javascript\">" +
Below is the issue :
From 12th Sept 2013, suddenly Markers stopped working and not showing in
the map. Please advice, whether there is any change in code before 12th
Sept 2013. Below is the error we are getting when we tried to search any
location.
