I would like to re-use FS9 flights in FSX (namely the series of Doherty's Difficult & Dangerous Approaches).In FS9 it was as simple as opening an existing flight.But in can't find this in FSX. There are existing (and add-ons) missions, but if I place one of the Doherty's Difficult & Dangerous Approaches folder into the FSX Missions folder, nothing shows up. If I put it into the Flights folder, still no joy.What am I missing ? Typically, the Doherty's Difficult & Dangerous Approaches include pairs of .FLT + .WX files. I try to understand the reason why in comparing the FSX missions folders, but can't get a clue of what goes wrong and what I'd do to make it work.Help! :(
