Problem with Airport Compile on STB Data Server in Flying W Simulation Posted Friday at 06:36 AM · Report reply Yes that's correct, and something I've seen before: Whenever I do, I try to improve the messages that STB puts out to explain the situation. In your case, it said: "FLW.STB.Utilities.StbDisconnectException: Invalid XML detected for airport SWTQ(Termas Pousada Do Rio Quente). Please check the runways.xml file found in the Prepar3D V4 installation folder at line 1718799 position 12, and the AFD/AFCAD file that implements the airport." Hopefully that helped you understand the problem. Thanks Simon"
