I'm join the battle but the notice command say "you need map 1.02+...something....". I though i can not play this battle cause cant imported the map.
I don't know what and how, a master member told me via chat room: "you should have command post ...try over google"
I don't know how to fix the problems, thanks for someone advise and linked me to the way!
Note: I BOUGHT GAME FROM STEAM
