Shadow Ghost of Poland

I'm sorry for writing here, but i don't know where i need to write this. I have a problem with map (f10) on steam version. I have this problem since the beginning of August. This problem looks like this when i'm in multiplayer or elsewhere when i click f10 my map is't loading no matter how long i will wait it will not load. I tried clicking in the settings, it didn't works. And now i don't have any idea what can i do. Please somone can help witch it. I will be very grateful.
