NOT GETTING DAYZ TO WORK keep getting error, please help

[gypsypirategod 0]

I used to play this mod so so much, This game is actually a reason i made a pc. Well one day i updated the game or something, cant recall, but i could never play again, i unistalled ALL OF ARMA, all add ons and everything and then reinstalled, nothing. Well i did that twice and gave up hope. Year later, yesterday, a buddy is playing and i gets on and i want to play with him because i have new life for the game, same thing, so i redownload the games again like i did before and try dayz launcher and even within steam as well and these are the errors i get, please help  http://tinypic.com/r/16ith7q/9  http://tinypic.com/r/4qgbbt/9

you're trying to join the server with different versions then you have in the second picture your trying to join a epoch server with dayz files.

 

make sure you run both arma2 and arma 2 oa with steam running as admin at least once and then install the corresponding mods for the game you wish to play
