*Which version of the game did you purchase? STEAM or RETAIL or MIXED: Steam, Combined Operations *Are you running an Arma 2 OA beta patch? If so what version?: I've ttried the following: 98866, 98836, 98809, 98443, 98220, 97771/71 and 97448/51. I've also tried using 1.7.2.6 and 1.7.3 on multiple servers *Which method are you using to launch the game? I.E Sixupdater/steam/batch file: I've tried steam and DayZ commander *What is the Error/Problem you're having? Please provide screenshots if possible: "This server is running an incorrect version of the server side application. You cannot play on this server. If you are the server admin please contact DayZ staff" http://i.imgur.com/NeWGB.jpg I receive that error whenever I try to connect to a server. The only server I can connect to are ones that are not connected to the hive (according to DayZ Commander). They spawn me on the coast with nothing. All other server with all other versions do not work. My self and 4 friends are all having this exact issue. We are wondering if the reason was because we were playing on a server when it restarted (we didn't see the message and it force kicked us) or if it is because we were playing on a server that is no longer part of the hive (which we used to). *Your PC specs: i5-2500k @ 3.3ghz 8gb ddr3 RAM sapphire 6870 64gb ssd for OS 1tb for storage (Arma2 + DayZ are here) *Your Operating System: Windows 7 Home Premium 64bit *Have you looked at these threads?: Yes http://dayzmod.com/f...d.php?tid=18588 My friends and I were all playing together the day before 1.7.3 came out and everything was working fine. For some reason we all started getting this error when we wanted to play the next day. We don't know if its related to the update or not. I've tried reinstalling DayZ, Reinstalling the Beta Patches, Reinstalling DayZ Commander, not using DayZ Commander, Reinstalling Arma2 + Operation Arrowhead. Any help is appreciated, Thanks!
