Running GPTask from Silverlight Error

A also posted this in Silverlight forum but thought maybe someone looking here might know;

I am trying to run a Geoprocessing Task from my Silverlight application.  But when I do it fails and gives the error:

Error Code '500': 'GPTask 'GetImagePath' does not exist or is inaccessible'

I can run this through my browser and it all works and I have checked in Fiddler and the commands are basically identical except the browser call includes the empty parameters for SpatialReference (and of course f=html).

This is not a secure service

Is there something I need to be setting that I am missing?
