I know I was supposed to uninstall them like that, but now that I have so many reinstalled I really don't want to have to uninstall/reinstall so
many of them . I read that there is a file called "WOAIDATAX" and I made sure to get rid of that before I reinstalled all the packages last time so I could try to completely start over with a new "WOAIDATAX" file. But the problem still exists.
About duplicate files, when I converted my WOAI files to FSX, it made a duplicate file in the same folder (scenery/world/scenery) with the suffix "FSX" added to each traffic file. Do you think that could be it? I don't think so because the problem was there before I did this.
When I said disappear, I meant that they take off and when they get far enough away from the airport they disappear like normal. So I don't think there is a problem there.
For an example of my problem, I went to Amsterdam yesterday and there were lots of planes at the gates and a long line for takeoff. But the whole hour I was there (with some fast forwarding) only two planes landed, I believe. That is not normal. There should be almost as many landings as takeoffs.
Hope you can help me and I gave enough information!
