There's a bigger forum post here called "forever stuck at loading screen" or similar that has a solution (5 pages long or something). First you need to downgrade from 95417 to 95389 (ftp://downloads.bistudio.com/arma2.com/update/beta/ARMA2_OA_Build_95389.zip). Please note, when you start opp A2:OA it will still say 952xx because that's the official release. You won't see 95389 unless you run @beta but that's not necessary, you can see the version-number in DayZ if you run the six-shooter and just click launch (instead of clicking on a server). After you've done that, download http://www.dayzmod.c...2.4-Weapons.zip and replace the two files in the zip archive. You should now be able to join almost all 95417/1.7.2.4 servers and about half of 95389/1.7.2.4 servers. Older servers won't work. And it might just be my impression but I have a higher success rate with the ingame browser than six-shooter. One thing that worries me though, I started playing on saturday and I tried for hours before I came across this solution and it took me some time to figure out what servers allowed me to join and who didn't. If they're tracking alt+f4 users I'm in a world of hurt because of this. I've played maybe 5-6 sessions and probably have 50+ alt+f4 exits, none from when I was actually playing.... I've yet to come across a player actually. Edit: Sorry, here's the correct thread where I read the solution that worked for me: http://dayzmod.com/forum/index.php?/topic/48723-official-1724-stuck-at-loading-screen/page__st__60
