Does anyone knows how to uninstall Just Flight Traffic? I checked under programs, I looked in community folder....not sure if it has different name somewhere or it's a mystery....Once in Sim I see it...but can't find where it is....

I have it but not installed. Do they have an online installer to remove it?

In general, have a look in %appdata%, program data, program files (both of 'em) and delete that stuff.

it will be in your add/ remove program
