Hi ! I just bought a coupple of your aircrafts (707 727 737 and 777) for fsx. I started by trying to install 737 and i booted fsx for a first test flight but all my gauges are black , landing gear is invisible and the aircraft control surfaces don't work exept the trim.. What could cause this ? I m looking foward to finally fly this bird

I am using FSX with windows 7

Thanks
Guillaume
