Commander revisited

I used Commander when I first started D-Star and I want to give it another go.  I have managed the download for my DVAP and have used the exe to set up the basics.  Can somebody remind me if I need to do anything else to the configs of the two G4KLX programs or is that all taken care of with the exe program (black screen).  If it is necessary can somebody give me some links to the necessary fields. I received an email telling me hostfiles were updated so I am doing something right.
