Problem with creating a Strategic Airport contract

I have been trying to create a contract for a strategic airport directly with a military bases MU corp and each time the following error message appears:

You do not need more than 1 airports. (1 airport per 999999 weapons)
You have 0 weapons and 1 airports.

Any helpful hints? I am not trying to contract it to my country but rather directly with the corp and, not that it should matter, my country does have plenty of strategic weapons and aircraft in stock.

We will look into it ASAP.
it will be coming Monday.

Thanks Andy! I was trying to make a Strategic Airport contract between ML Enterprise and the Military Base MU corp located in MittensLost.
