I have a brand new notebook and downloaded day z after i bought the required armas, but whenever i try to join a server it say- Files "C: program files (x86)/steam/steamapps/common/arma 2 operation arrowhead/expansion/addons/musice.pbo","common/wheeled.d.baf.pbo" are not signed by a key accepted by this server. To play this server remove -forgot this word- files or install -another word :P- accepted keys by this server. :huh:
