Kinect hand cursor and User Viewer not showing

[sk8ergirl]

I followed one of the tutorial to have hand cursor and when I run my app I couldn't see the hand cursor or the userviewer
I was expecting something like this http://dotneteers.net/cfs-filesystemfile.ashx/__key/CommunityServer.Blogs.Components.WeblogFiles/vbandi/image_5F00_2FF95AAB.png

but nothing happened when I run my programme I only saw the button I spent hours trying to fix it but I didn't know what is wrong with my code
here is my code

<Window x:Class="handMovement.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:k="http://schemas.microsoft.com/kinect/2013"

        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <k:KinectSensorChooserUI HorizontalAlignment="Center" VerticalAlignment="Top" Name="sensorChooserUi" />
        <Label x:Name="KinectStatus" Content="Kinect status change" 
               HorizontalAlignment="Left" VerticalAlignment="Bottom" FontSize="15"></Label>
        <k:KinectRegion x:Name="kinectRegion">
            <Grid>
                <k:KinectUserViewer VerticalAlignment="Bottom" HorizontalAlignment="Right" UserColoringMode="HighlightPrimary" PrimaryUserColor="green" Height="150"
                k:KinectRegion.KinectRegion="{Binding ElementName=kinectRegion}" />
                <k:KinectTileButton x:Name="ClickMe" Label="Click Me" Click="ClickMe_Click" VerticalAlignment="Top" HorizontalAlignment="Left"></k:KinectTileButton>
                <k:KinectScrollViewer VerticalScrollBarVisibility="Disabled" HorizontalScrollBarVisibility="Auto" VerticalAlignment="Center">
                    <StackPanel Orientation="Horizontal" x:Name="StackPanelWithButton" />
                </k:KinectScrollViewer>
            </Grid>
        </k:KinectRegion>

    </Grid>
</Window>
