Can't get spatial query REST soe to work

[TimRourke]

I compiled the sample solution for the REST SOE walkthrough for .NET. I followed all of the steps to register and install the components on the server. Even after several iterations, the result is the same: the properties drop-downs never show up in the ArcGIS Service Manager. In Internet Explorer, when I try to enable the SOE for the Yellowstone map service, I get the following error:

"Message: Sys.ArgumentException: Cannot deserialize. The data does not correspond to valid JSON.
Parameter name: data
Line: 5
Char: 62099
Code: 0
URI: http://arcGisHost/ArcGIS/Manager/ScriptResource.axd?d=fm0WXCTqHSeU0hKM6Swwg4U9FpaFqweYA8-wOt2Mg9aRL9..."

This is where SOEs failed for us in 9.x, but this time we got an error message. Has anyone seen this and got past it?
