Is there a way to completely reset UT2. My version is only displaying Airbus A 321 traffic in a only a few liveries and most of it is parked up. There is little or no activity at even the most busy airports. Heathrow looks positively boring for instance with only a couple of ground movements and almost no take-offs and landings. I don't remember fiddling with the settings. I have gone through my UT2 settings as much as I can to sort this problem. Maybe I have inadvertently messed this up myself but I would appreciate some help. BTW I have searched here and elsewhere for a solution in case people think I ma being lazy.

Uninstall and reinstall?

 

UT2 has it's own dedicated support forums you should try posting there first the UT2 team is usually very responsive

I think it takes a roundabout 10-15 minutes to get all of the planes popped up and for traffic to be starting in and out. If you start out the flight in a busy airport, wait a while and see what happens.
