Error when joining servers.

[A Random Pointless Name 0]

Okay so I have been playing DayZ for awhile now but I have never seen this error or had it before. It pops up when i'm in a game lobby and click "Ok" to get into the game. It starts to load but then it stops and goes to a black screen that says "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." Everything is up to date and I have the betapatch installed. I tried reinstalling Arma OA and it still dose it. Also I recently installed the NWO mod with Addon Sync 2009 but I don't see how that would have anything to do with it but this error never poped up before before I installed NWO. Any help would be appreciated.

Is it happening on all servers it seems like you have an outdated version or beta. You may need to use dayz commander (as its just easier) and hit the update button check your versions there and update as necessary.

Well it just started working after i uninstalled Addon Sync 2009. I don't really get how that had anything to do with it but i'm not complaining. Thanks for the help anyways.
