I have a friend with the same issue and it doesn't appear to be router related. We think this because another computer connected to the same router does not have the same issue, so it appears to be computer related. If the Battleye client is not responding, is there a way we can check the client or its connectivity? When we manually update DayZ BE (found here http://www.battleye.com/download.html), it appears to be a single .dll so we're unsure how to check the client. It appears to 'initialize" on connect. We've also turned off windows firewall (the only security software on the computer) in case it was blocking the client. Any other suggestions?
