So using STEAM. downloaded Arma2/Arrowhead Downloaded all the DayZ shit.. and put them in the dayz/addon folder in the arrowhead directory did "-mod=@dayz -nosplash" in the arrowhead properties and whenever i log on i get the error "You cannot play/edit this mission. It is dependent on downloadable content that has been deleted". Pretty sure i put everything in the right places.. and when you click "Launch Combined Ops" is it supposed to launch the actual game or not? because mine doesnt launch the game just a black command window comes up for a second then dissapears.
