Can't get into DayZ server

[Kylerr (DayZ) 0]

When I try to join the DayZ server my friends are on while launching through Steam, it says that I have the wrong version (1.62) and that the server is running 1.62.103419. The funny thing is, last night I launched through SixLauncher and although it said I had 1.62 while the server had 1.62.103419, it let me play just fine. Then, my Windows updated while I was playing and restarted my PC. Now when I try through SixLauncher, I can log into the lobby fine, but when I try to get past the next loading screens and into the game, it takes a long time and then tells me that something went wrong and to disconnect and try again. Now I can't log into the server through Steam or through SixLauncher. I seem to be having issues with connecting to other servers as well, but the only server I want to log into is this server. Help? Also, I am very sorry if the answer is stupidly obvious as I'm pretty bad with this sort of thing, but I have looked around a bit and have not found a solution. Any help is GREATLY appreciated.

This is what it shows when I try to log into the server through OA on Steam

I understand that I have the wrong version but I have no idea how to update my game to the required server version.

Is the problem the wrong A2Beta version, or the wrong DayZ version?

I... honestly have no idea. How do I know? Sorry, I'm so lost ;_;

You have DayZcommander, right?

Go to settings and you should see this. Now click "install" on Arma 2. This will update your game.
