Thanks for that, did all of your stuff, and still no go, Get the launcher window, go start, crash get a tiny window with numbers in it, and some text sometimes I can read jet, so the jetlog may throw some light on it???
In my content I have some 104 with missing dependicies, some with zzzz on them, Nothing showing faulty. My route is about 12mb big and I have been at this current route for 6 months. Have lots of backupups.
I have a sneeking feeling and this as happened on previous route builds that after a certain size the trainz program just fails. Maybe I am being too ambitious with my routes.
