Custom map is broken on satellite view, does not show satellite imagery. Any ideas, what's wrong? Overlays are also broken - they're not transparent.

Code:

    <div id="map_canvas" class="grid_8 omega" style="width:460px; height: 420px"></div>
    <script src="http://maps.google.com/maps?file=api&amp;v=3&amp;sensor=true&amp;key=my-key-is-here" type="text/javascript"></script>
    <script type="text/javascript">
        function initialize() {
            if (GBrowserIsCompatible()) {
                var map = new GMap2(document.getElementById("map_canvas"));
                map.setCenter(new GLatLng(52.229676, 21.012229), 13);
                map.setMapType(G_HYBRID_MAP);
                map.setUIToDefault();
            }
            var geocoder = new GClientGeocoder();
            function showAddress(address) {
                geocoder.getLatLng(address, function(point) {
                    if (!point) {
                        alert('Nie mozna znalezc adresu: '+address);
                    } else {
                        map.setCenter(point, 13);
                        var marker = new GMarker(point);
                        map.addOverlay(marker);
                        marker.openInfoWindowHtml(address);
                    }
                }
                );
            }
            showAddress('some address goes here')
        }
        $('body').ready(initialize);
        $('body').unload(GUnload);
    </script>
