It is loading together with FSX and is running during the setion. It is killed when I exit FSX
I'm sorry, but I really don't know what so say now, this means it's working absolutely fine.
Looking at your log, however, there's something strange, it seems it runs, but it doesn't do anything.
Can you please enable the log again, run FSX, go to an FSDT scenery, wait for the scenery to load (even if main buildings are missing), then exit from FSX and post the log ?
