[amenofiiv 0]

Hi everyone,today it's happenend a weird thing to me, hope someone could explain it.. Installing a flightplan I've noticed that on evai there was a better aircraft that the one I've owned. So, I've downloaded and istalled. In the same time I've deleted the PAI aircraft and renumered all aircrafts that follow on the aircraft.cfg I hope you follow me!I've discovered (with my surprise) that all aircrafts that I've renumered aren't showned up! :( I think is a issue of mrai installer (I use mrai), there is anyone with my problem too? There is anyone with the solution (obviously the most simple solution is re-install all flightplans with aircrafts disappeared!)?Thanks a lot, I hope you follow my english! ;)Vittorio
