i had the same problem. i reinstalled everything like they said. doesnt matter depending on what server you want to get into if you use battleye. steam doesnt matter if its on and it helps. use sixinstall/update to load dayz. then i right clicked steam in the tray to open OA. went to expansion and added Dayz then it restarted. once it did that i went to mp and found a server. some servers are shit but make sure when you go to mp that dayz is in the expansion dealie. after that i got into some servers. avent used sixs servers yet. but always make sure dayz is there when you play or itll give you that stuff is deleted deal. if you have problems ill help if i can.
