I found the problem, it is the language, in spanish when I select a OOB the program crashed but if I change to english, the scenary works fine, and if I return to spanish the scenary crashs again.
Many thanks.

The game crashs both ways (Air Units from the drop down menu or the Air OOB right side button); there is a third way (unit formation) that crashs too. Now, I realized that it crashs with all OOB´s within this scenary (not only air).

Yes, I have the latest beta 4.0.1.23 (now official).

Regards.

The game crash when you select air OOB playing with the allies.

I want to change the counters of the North Africa scenario with your counters mod, how can I do it?
