Er.. um... did you see this thread pinned at the top? Probably best to post in the J41 forum. :( http://forums1.avsim.net/index.php?showtopic=266159

GeorgeI may be wrong, but isn't this the PMDG Jetstream JS4100 Forum? [TURBOPROPS].Did you mean a "Non-specific" aircraft forum, ie PMDG Licence issue"?Happy New YearKev Townsend

Yes I have a connection with internet. I have tried to fix this the whole day, but no succses...What am I suppose to do???I have done everything... I think.Best RegardsPer St

What about if i uninstall FSX and reinstall it, all from scratch???Could that fix the problem???regardsPer St

Instead of FSX reinstall, first try just uninstalling FSX SP2 then reinstalling. That has fixed a few problems but not this one yet.You should send an email to pmdg support while you are trying to fix it.
