Map load with the extreme COD4 MW v2.0

I downloaded a map. from another server and would like to run the map on our server.

The problem I have is, I cant seem to hit and kill the enemy on the other side of the map. When I run bots, I can shoot the bots on my side of the map however not on the opposite side of the map.

If it's a sniper map, i think u have to run a sniper config

you need more than a cfg - you need sniper rifles that have been edited to shoot projectile ammo, and have been edited to shoot & hit targets at a long distance. Here's the long range sniper rifles with stable scopes HERE
Just unzip the file and drop the weapons folder into your z_x4.iwd - it will over write the existing sniper files.
Use winrar to open the z_x4.iwd - you'll see the weapons folder - drag n drop this weapons folder to it.
