I've been trying to update my AI traffic in FSX SE as I have only been using World of AI packages, which are outdated (2000s - early 2010s). Because of this, I've searched and come across AIG AI Manager, which fits what I want to do. I've already reached the point where I can open the program until the title part (not the actual UI). Unfortunately, I cannot proceed as when I want to select FSX in the drop-down menu it's empty. I tried to click the select (green) button and it just quits the program.
Am I missing a step? Any help would be appreciated.
