I have made some minor changes to an existing protocol from Skyline for the AppearTV X20 platform. I am trying to test my changes but no matter how I attempt to add the modified protocol (xml, dmprotocol, dis publish) it gives the same worthless error message "Error Adding protocol" this might be helpful if it had any indication what the error was. My sln builds and the xml file parses in the dis tree so I'm not sure what else to check.
