There is a couple potential problems. First, you must install a PlugIn from Adobee to view your model in the wM Monitor -» SVGView.exe. It is explicitly stated in the installation guide.
Also, after marking your model to be «monitor» in the wM Modelor, you might have to enable it - sometime - using the Flow Services in wM Developer (WmMonitor Package). It has happened to me a couple times.
