[Aragorn1963]

I've taken a look into this campaign through FMB. I'm not sure whether what I found is useful, but here it is. I didn't find a Players aircraft (must be there, but too many planes to check them all), so I chose one. After that the campaign loaded without problem. So I did it with every mission of this campaign, and my problems seem to be solved. For what it is worth, hope it helps.
