Dayz Epoch Chernarus Mod Skachat

How do I FIX this god damn error.... I have uninstalled Arma 2 + Arma 2 OA 3 times have installed dayz commander 3 times have downloaded Dayz epoch 3 times and still get this error. I have verified all my files in steam I have run both games through steam....

I bought Arma2 OA about 3 days ago and for the sole reason of playing dayz mods mostly epoch. So i got dayz luancher and all that stuff but when i try to luanch say Epoch i know it works becuase it says DayZ Epoch when it would normally say Arma2 in the loading screen, But when i try to join a server i get and error saying what tjis thread is about or sometimes itll just say Addon Chernarus needed. I only have Arma2 OA not the regular game as well i dont know if thats the problem. ALl i wanted to play is dayz and a friend said that all i needed was OA and not both the regular game and OA i dont have enough money to buy the regular version and most likely wont for a LONG time. But i shouldnt need both if i do thats VERY dumb and if i do i should be able to get the Regular version for free since i bought OA. so if anyone has any ideas of what i should do PLEEEEEEEEEEEEEEEEASSSSSSSSSE help me i am very desperate!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :( :( :( :( :( :( :( 59ce067264
