Dashboard Action Button not working for Services

Hi. I watched the video on Dashboard actions and trued to add a Dashboard action to Get Monitor Status, to a Windows Service object that I am monitoring. I must be doing it wrong because I always get this error:

Initialization of a module of type "MonitorStateChangeProbe" (CLSID "{8951E718-F2DD-41DF-9D3D-284C4B3EC8DB}") failed with error code The parameter is incorrect. causing the rule "System.Health.GetMonitorState" running for instance "- Test" with id:"{1E356374-79CF-1F1E-118F-16F97C4D1DF6}" in management group "XXXXXXXX".

Having said that, “Reset State” seems to work…
