I have small problem , I have the B 747-400x and the MD-11, My problem is wend I change from the 747 to the md11 the md 11 instrument pane is black none of the instrument come on the only way is back is wend I live the fsx and them reloded. it seen that I have to get out and them return to be able to see the panel. it also hapend if I change from one livery to a nother.

I don't load two different complex aircraft simulations (read: pmdg) in the same FSX session. I always restart FSX when going between aircraft like the 747, MD11 and JS41.Changing livery doesn't seem like it should cause a problem, but in FSX if the livery change is keeping the same engines FSX will do weird stuff like smoking engines. Not recommended either.If the MD11 doesn't load correctly from a fresh start with FSX, run the installer and select repair for the aircraft and the C++ redistributals.
