Courage (DayZ)

I've had arma 2 for a file and dayz ever since there were only around 3000 players. But I fell out of it more recently and so I uninstalled all my arma 2 folders. Now, some of my close friends are playing so I wish to re install the game. But now, it seems impossible. I got all the sprocket files and arma 2 OA works perfectly. But when I tried to install arma 2 things started to go awry. I finished sprocket after a longer than normal wait and I started to run the arma2_110_setup when around 2/3 of the way through it starts giving me errors saying it can't install a large amount of files. Some don't matter for dayz but the big wammy is it does not install chernarus.pbo. I can't figure any way to get around this. Any help please?

I've been having the Deleted.Chernarus problem since the new update. This game hasn't had this problem since I started playing but with the new update the game is impossible to play because I get kicked off with this message. I fixed it once but the same fix won't work anymore. I've tried reinstalling Day Z, Six Updater, but not arma II. This is also different since the new update. When I ran CO I use to never get the start screen but now I do. I don't know if that valuable info.

It confuses me that they will stop global chat without fixing the direct chat problem. It becomes impossible to communicate without a mic. Why would they do that? How did they come to that decision?
