Having downloaded Arma III Beta from Steam, multiplayer mode worked fine after installing BattlEye. However, in the past 48 hours the mode has failed to connect with any server. The problem appears not to be my computer or internet connection, which is strong. Now what happens when I click on 'join' is that there is no prompt. The screen merely switches to an outline map of Stratis and the words 'group channel' in the bottowm lefthand corner. Nothing else happens. Please advise.
