I purchased the Steam version of Arma2 and Arma:OA with the beta patch (1.7.7.1). My rig is running Windows 7, and it is most definitely capable of handling DayZ. I just started playing Day Z yesterday and after half an hour of troubleshooting (verifying the steam cache, etc.), I got into a game for a solid hour or two. Today, however, Steam said that Day Z needed an update and now I keep getting this error when joining the server: After I hit Continue, I start joining the server, but it stops loading with the message "Waiting for server to start authentication." Then when that's finished, the screen goes black, and I get this: Anyone know what's going on? *****EDIT***** Found out the problem. 1.7.7.1 has no servers that support the game yet.
