I have two hard drives in my PC, one with Windows XP 64-byte and the other with Windows 7, 64 byte, the two operating systems have the FSX with Captaisim 767 of the problem after installing lights Cheyenne is Windows 7, Windows XP when I open the planes are perfect because in that operating system have not installed the darn plane

I uninstalled the 767 of Windows 7 and as usual there is no way to fix it, I copied the aircraft.cfg and panel.cfg and does not solve the problem,
Think it is good idea to restart 2 days ago?
Greetings
