It would help if you actually gave a description other than you can't play, such as what error you are getting. I will assume that BattlEye is just not updating so you can;t play because of this.Try going to dayz properties in steam, click local files tab, then hit verify integrity of game cache. This will make sure everything is updated, even BattlEye. It may say nothing downloaded but it will still have downloaded stuff.

Hello, the problem is not there. I checked the game cache , uninstalled and reinstalled the game, download the updated version on the official website BattlEye , changed my firewalls. Nothing has any effect on the problem. Even little Vilayer.com connect effortlessly on my server.

Hello Zallan,

In this case I would recommend that you contact BattlEye's support in order to figure out why the BE client is not responding: http://battleye.com/support.html
