etops,
there might have been a file corrupted with megascenery... The reason is, I have megascenery New York and North East (all of them actually) and still have no problems. I just flew into JFK this morning from Heathrow and had about 50fps at landing with NY Megascenery, FSDT JFK, and AS6 running producing extremely poor visibility...only 800ft! Sucky first approach into JFK...
But only 'cause I couldn't see the airport! ha! Had to use autoland. Anyway, the point is, it works for me, so, maybe try reinstalling megascenery and putting FSDT JFK priority over megascenery.
