Ahh, now we are on to something! I just tried reinstalling build 117 and the gm_enhanced.prn file is dated 30/03/2010. This seems to have the PID available. I think the updater or the installer may ignore the current Registry settings and not place files in the registry set locations, but default to other locations. Sio even if you select to keep the current settings, it doesn't do that :p. I'll see how I go now. Thanks guys.....
