Stalingrad part 1 problem

[senseispcc]

I did finish Staligrand part 2 and the Moscow campaign some time ago and begun the Stalingrad part 1 campaign but never completed it at the time.

Now I whant to continue it but I am faced with a big problem: when I try it the camapign (game) ask me to chose a terrain to fly from but does not propose any?!

How do I correct this? 

I verified, I am at the end of part one of the Stalingrad part one campaign.

Itried again after asking Steam for verify my files and it worked like a charm, I do not know it was this or a uato repair but it works.  

 Missions more in my campaigns for this day flying.
