Landscape1 USA Soils Query Task Security

I am developing with the Web Silverlight API. I have no problem generating the token required to view the USA Soils Units layer. However I am having security issues with the Query Task. I guess I assumed having the token for the layer was enough to execute the query task. Here is the code executing the query:

Private Sub MyDrawSurface_DrawComplete(ByVal sender As Object, ByVal args As ESRI.ArcGIS.Client.DrawEventArgs)         ResultsDisplay.Visibility = Visibility.Collapsed         MyDrawObject.IsEnabled = False         selectionGraphicslayer.Graphics.Clear()           Dim queryTask As New QueryTask("http://http://landscape1.arcgis.com/arcgis/rest/services/USA_Soils/MapServer/0")         AddHandler queryTask.ExecuteCompleted, AddressOf QueryTask_ExecuteCompleted         AddHandler queryTask.Failed, AddressOf QueryTask_Failed         queryTask.Token = "NbSci3CSDr8ShEb1EAuGw3ykma8u-Z9CmFnlf0EZ0CH2tR0sz3HhaIaLOyQFGmbqKuZV89jEMs0CiLkjlX0p7pMb7vgykCFtegR7EIuzgXv1DDbfEgahaeQX3FPGXk7NY85N4oVwWBGlop_gCTNwuA.."           ' Bind data grid to query results         Dim resultFeaturesBinding As New Binding("LastResult.Features")         resultFeaturesBinding.Source = queryTask         QueryDetailsDataGrid.SetBinding(DataGrid.ItemsSourceProperty, resultFeaturesBinding)         Dim query As Query = New ESRI.ArcGIS.Client.Tasks.Query()             ' Specify fields to return from query         query.OutFields.AddRange(New String() {"mukind", "areasymbol", "aws025wta", "aws050wta", "aws0100wta", "aws0150wta"})         query.Geometry = args.Geometry           ' Return geometry with result features           query.ReturnGeometry = True         query.OutSpatialReference = MyMap.SpatialReference           queryTask.ExecuteAsync(query)     End Sub

Results in the following error message

{System.Security.SecurityException ---> System.Security.SecurityException: Security error

at System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult asyncResult) at System.Net.Browser.BrowserHttpWebRequest.<>c__DisplayClassa.<EndGetResponse>b__9(Object sendState)

System.Exception

I was able to execute the query form
