Mine is doing the exact same thing. I deleted the .cfg file and then ran p3D. it ran good before and after I deleted the file. When I try to adjust any settings the bar loads to 100% then it just crashed. Have you figured anything out yet or should we probably put in a ticket or it.

EDIT: When I tried to start it a couple times it began to work correctly. I noticed higher frames as well when compared to flying at the same airport with the same settings.
