The general support subforum would be okay -> http://www.flightgea...wforum.php?f=17
And if not, I or the other moderators will simply move it (no need to fear the moderators at our forum :P)
Please tick the "Show commandline" option on the last page and copy&paste the contents of the box that appears. That'll allow us to see what options you've set (apparently there are some options missing/faulty).
Cheers,
Gijs
