Hi, i have some questions about this special survival maps 
  
recently i played a survival game on cnc, it didn't go well   
after the round i wanted to play the survival map, that i got from the last game, with my friend, but we wasn't able to play it correctly, in-game i got some Messages from missing files or something, i dont know, and after a while the game crashed... 
  
My questions are: 
  
How I Setup a survival map? Maybe I forgot something?   
  
And about the missing files, did i have to download something from the internet, so the map is working correctly? 
  
Thanks.
