unable to load multiple fusion table layers on google maps

Question

I have used fusion tables to load multiple FusionTableLayer on google maps . But today suddenly i found out that i was unable to load more than 5 fusiontablelayer at a time in a google map api.

The js code is

<script type="text/javascript" id="telerikClientEvents1">
        var layers = [];
        var map,jsg;
        var layerName, ctr = 0;
        jsg = new google.maps.FusionTablesLayer({
            query: {
                select: '\'geometry\'',
                from: '1jWdnG9b_mQP03PowydJufDpztjWo0AIipDpTjSU'
            }, suppressInfoWindows: true
        });

        function initialize() {
            var mapOptions = {
                center: new google.maps.LatLng(21.807007904182043, 83.90197012695307),
                zoom: 10,
                mapTypeId: google.maps.MapTypeId.ROADMAP
            };
            map = new google.maps.Map(document.getElementById("map_canvas"),
            mapOptions);

            // District Layer           
            jsg.setMap(map);

            google.maps.event.addListener(layers[2], 'click', show_info);
            google.maps.event.addListener(layers[3], 'click', show_info);
            google.maps.event.addListener(layers[4], 'click', show_info);

        } // End of INITIALIZE

        layers[1] = "";
        layers[2] = "";

"Limits

You can use the Maps API to add up to five Fusion Tables layers to a map, one of which can be styled with up to five styling rules."
