same issue guys.... here is another thread on it... http://feedback.dayzgame.com/view.php?id=12499&nbn=2

uninstalled battleye, dayz, steam.... deleted every instances of it... including registry. re-downloaded everything. Still having the issue. Everything worked on august 15, then the problem started on august 16. nothing changed on my system. problem is with one of the three i listed... i think others will agree... this needs to be fixed asap or give us our money back.

I also started having this issue Aug 16, 2014. I was playing Aug 15 without any problem, then the next day, the exact same issue everyone is having is now happening to me. Yesterday, I uninstalled dayz, battleye, removed everything from the registry, complete clean wipe, rebooted, re-download dayz, reinstalled everything, and still doing the exact same thing.
