Solomon Islands map problem

[Hornet]

Hi! I have a problem with Solomon Islands map. Every time I choose this map it loads to 90% and then suddenly stops and is unable to load more. It shows up a message which says "Mission loading failed: Mesh3do/humans/Paratroopers/Russia/mono.sim not created". Every other map is loading without any problem, except this. The map does not want to load both online and offline. I have IL-2 Sturmovik 1946 4.12.2 patch, no mods. I searched for this on internet, but I couldn’t find anything. Can somebody help me?
