Yes, I have the same thing whenever I set up a mission involving the BF109E-1. I can set up waypoints for it, but when I try for instance to change any parameters or assign custom skins to other similar BF109E-1's in the flight, then the whole game freezes and gives up the ghost.

I thought it was just me and my set-up and since there are generally enough other models of Bf-109's (too many even) I just shrugged and used another model Bf-109.

I suppose the BF109E-1 flight model is somewhat different from the others, which is a shame it doesn't work for Spanish Civil War missions.

But if there is a fix, then I'd be happy to learn about it.
