So which game are you playing ? CoD4 or WaW, ? that appears to be a WaW map you are trying to use. If it is indeed a WaW map you wish to use on CoD4 it would need to be re-formatted (? brain freeze) to be used in CoD4 and I have no idea how to do that. If that is what you are trying to achieve then try asking SnR if they have released that map in that format.
