I've tried for the past 4ish hours to get this working with no avail. I've uninstalled both versions of Arma 2, reinstalled them, patched the beta, extracted all necessary files to /@Dayz/Addons, run DayZBeta.cmd and it doesn't even open. When I open Combined Operations through steam I can't join 1.7.1.1 servers EVEN THOUGH I HAVE THAT CODE IN MY ADDONS FOLDER. I am so unbelievably frustrated that I'm trying diligently to not swear in this post. :@
