Its been a long time since I last posted haha. But I recently purchased the KLAS product and installed it. I activated it in game and it only showed the jetways. So I restarted fsx and had the same problem. I checked in my Addons tab in game and there was no couatl option where they used to be. I decided to try and reinstall the package and when I do it comes up with an error saying that Couatl is running and I need to close it and it wont close when I tell it to. Even when I say ignore, it comes up with another error where it had trouble getting access to the couatl folder. Still ran into this problem when I tried to run installer as an administrator. I also installed Megascenery Las Vegas after installing KLAS for the first time. Maybe that has something to do with it?
