Hello guys
I have found a way to get around the "Loading" screen whenever you attempt to join a server.
Firstly download the latest 1.7.2.5 files, don't use the six updater link, instead use the mirrors
http://dayzmod.com/?Download
And also download the current build
http://www.arma2.com/beta-patch.php
(Highlighted in green at the top of the page)
DO NOT INSTALL YET
After this has been completed, open six launcher and then verify.
open
C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead\@DayZ\addons
Replace the files inside of "addons" with your newly downloaded 1.7.2.5 files. You should see a 2mb difference.
Now run the latest build setup, once completed launch the game through six launcher and try joining a server.
