mvm map problems

[Lunartik]

I have been trying to compile an mvm map with a bunch of tanks for testing. Im not actually making a map im just trying to make a .pop file work that I got from here but when I start the Map it says
Can't open scripts/population/mvm_ghost_town_1.pop.
Parse Failed in CPopulationManager::Initialize for scripts/population/mvm_ghost_town_1.pop
I have created a nav mesh but I cant get this to work. I will attach the files.
