Survival maps problem

[Traxx]

Hi, I'm playing Yuri's Revenge (Origin edition) with installed cncnet. Everything works fine except survival mode. I've downloaded many maps with this mode, but everytime game crash. Sometimes immediately, sometimes after minute or few minutes. I think I'm missing some AI files or something. I'm playing solo, not with multiplayer.

My current version of cncnet is 3.76

Thanks for help
