Can not load bing map

Hi Team,

The map worked before. But recently it stops working with this exception:

Could not find file: …\AppData\Local\Temp\MapSuite\PersistentCaches\BingMapsMetadata.xml.

My codes are:

            wpfMap1.MapUnit = GeographyUnit.Meter;
            proj4 = drawFeature.Prj4Meters();
            pointShapemin = (PointShape)proj4.ConvertToExternalProjection(new PointShape(120, -14));
            pointShapemax = (PointShape)proj4.ConvertToExternalProjection(new PointShape(160, -42));
            wpfMap1.CurrentExtent = new RectangleShape(pointShapemin, pointShapemax);
            LoadMaps loadMaps = new LoadMaps(wpfMap1, ProjectContext.BingMapsKey);             
            DefaultLayerStyle(); 

public LoadMaps(WpfMap wpfMap, string bingMapId) {

        BingMapsOverlay bingMapsOverlay = new BingMapsOverlay(bingMapId, ThinkGeo.MapSuite.Wpf.BingMapsMapType.AerialWithLabels);       
        bingMapsOverlay.Name = "Bing Maps Aerial";
        bingMapsOverlay.ApplicationId = bingMapId;
        bingMapsOverlay.IsVisible = true;     
      //  wpfMap.ZoomLevelSet= new ThinkGeo.MapSuite.Layers.BingMapsZoomLevelSet();
     
        wpfMap.Overlays.Add("bingMapsOverlay", bingMapsOverlay);

        

    }

Do you have any idea to fix that?

I’m using ThinkGeo.MapSuite 10.4.0

Thanks
