About a week ago my traffic controller for MSFS 2020 would start up then just quit. I don't know what happened. My aig manager did the same thing. I put that in its forum group.

Please check Windows Event Viewer for errors with AIM/TC and post them here
I didn't find any for the aig manager. Here's what I had for the traffic manager.
open:
%localappdata%\AIGTech
remove every AIGTC directory in there and try again
That did the trick.
Thanks.
