I have now installed the test software and it installed fine and the Humax still works so those concerned it might get "bricked" should not be worried. The box does not lose any recordings but the recording schedule was deleted.
It did catch me out with a question about Network, which I thought meant WiFi network, but actually lead to it doing an Automatic Tune of stations.
That is about as much as I am prepared to state here ...
