Hi Markus,
Good news. I think I have it up and running. My search found 4 different locations for usercfg.opt. I renamed all but one and ran Navigraph Hub. This gave me a screen as per my OUTSIDE picture. I couldnt do anything other than add the Fenix. I then renamed the file in WpSystems back to usercfg.opt and it worked. The proper Navigraph Hub appeared with options to update AIRAC where needed.
Thanks for the assistance. I think the issue was a wrong usercfg.file. What a tricky problem.
Updating the Fenix now.
Cheers
PC
