I just purchased this and installed, and found that I was missing panels..
I have tried to "Repair" the installation & Reinstalled and have the same problem.

In the Virtual cockpit the center pedistal is missing all the radio displays and the labels for the engine fire switches.
The overhead 2D view...
The IRIS and the Pac panel are black panels.
The Animation panel won't open
The Radio panel when it opens is a black rectangle.
The EFIS panel won't open.

I think I've got it all...

I am running the following...
   Windows Vista SP2  64 bit
   AMD Phenom Quad Core 2.2GHz
   6.0 GB RAM
   ATI Raedon HD 4650
   Realtek HD Audio
   FSX Gold W/Acceleration
