Google map API error: Object doesn't support this property or method

I am using Artem Google map control in my webpage. I create markers on the map after doing a geolocation mapping for a list of IP addresses.

     <div id="mymap">
    <cc3:GoogleMap ID="GoogleMap1" runat="server" Width="1400px" Height="700px"  Latitude="42.1229" Longitude="24.7879"
Zoom="3" BorderStyle="Solid" BorderColor="#999999" BorderWidth="1" EnableScrollWheelZoom="true" EnableContinuousZoom="True" ShowScaleControl="True">
    </cc3:GoogleMap>
        </div>

This page keeps refreshing after every 1 minute. It all works fine for sometime, but after a while, an error starts showing up in all the browsers.

IE: Message: 'sa' is null or not an object Line: 439 Char: 108 Code: 0 URI: http://maps.gstatic.com/intl/en_ALL/mapfiles/362b/maps2.api/main.js

The map is still displayed with all its markers. But I can't zoom or drag the map as it becomes static. Also, the infowindow on the markers don't open.

Seems that you have reached your geocoding limits.
