No cameras available

I am trying again with SecuritySpy and the plugin.
I had already installed SecuritySpy and now the trial expired; I can see both cameras and also access the web server, but in Indigo, after having created the server, the list of cameras is empty; is it because of the expired trial? I do not think so, btw

I haven't used SecuritySpy in a long time, but that was the behaviour at the time. I guess it makes sense from a business perspective.
