So far I have spent 10+ hours of my life attempting to play this game on the server my friends play on. I have read every single help/support thread out there, I have tried all the fixes, hacks, tricks, etc. I have reinstalled the game and done it all again. I am so incredibly frustrated with this game I am ready to call it quits and not play with my friends. I am posting this as a last effort. I will list all the things I've tried in the order I tried them and maybe someone here can offer me some advice? Goal: Play on private server that my friends are on Steps taken: 1) Download Arma 2, Arma 2 Op Arrow. through steam 2) Run Arma 2 normally via steam to complete installation 3) Run Arma 2: Combined Operations via steam to complete installation 4) Update Arma 2 Op Arrow to latest beta via http://www.arma2.com/beta-patch.php (96751) 5) Install dayZ 1.7.2.5 (Server is still running this version) -I have done this step in the following ways: --Created @DayZ dir and placed files in directly from torrent --Installed via DayZ Commander --Attempted Play WithSix but this will only allow latest version to be installed --Modify _runA2CO_beta.cmd with the following run line: call "%_ARMA2OAPATH%\Expansion\beta\ARMA2OA.exe" -nopause -skipIntro -nosplash "-mod=%_ARMA2PATH%;EXPANSION;ca;@dayz" "-mod=Expansion\beta;Expansion\beta\Expansion" -window -cpuCount=2 -exThreads=7 %1 %2 %3 %4 %5 %6 %7 %8 %9 Here are my current issues: 1) Before I update Arma 2 CO to the latest beta I can see the private server in the main server list (obviously can not play though), After beta update I can no longer see it in the main server list 2) I add IP and port via Remote button, I am able to enter server password and it attempts to connect. I see this Error: "'You cannot play/edit this mission, it is dependent on downloadable content that has been deleted.dayz_code, dayz_weapons, dayz_equip etc.'upon joining any DayZ server", I know all the guides say that this is due to incorrect DayZ installation however I have followed every direction of multiple installation forms to the T. I don't understand how to fix this if it is a major issue? 3) After seeing the error message I am booted from the lobby with no reason/message and returned to the main server list. The wiki's say this is due to battleeye, I have properly reinstalled this via steam on both Arma 2 and Arma 2 Op Arrow. This does not change anything Note: This happens on any server i attempt to join, not just the private server. Any help anyone could provide me would be most appreciated as I am simply out of ideas and frustrated beyond belief.
