Aircraft preview does not work

[Kianoni]

I get the same results, I only get a glimpse of the selected aircraft and then I only see the background and very often this leads to an almost complete halt where I can't even move the mouse cursor - same for customizing pilot.

In my case I can view all planes, takes ages for them to load to full detail, but only the first British pilot will show up for me. All others just result in a black view port.

my case it CTDs ,very unstable code atm

CTDs for me as well, instantly when trying to increase the weathering of the plane, and sporadically while only changing planes.

my rig:

Intel i7 920 quad.
ATI radeon 4890.
3gb ram
windows 7 (directx 11)
