Yup. This is happening to me too. Brought it yesterday. I've been searching for solutions for ages. I've tried reinstalling it. I've made sure I'm on the internet tab. I raised the max ping to 1000 to see if that would help. It didn't. I've tried deleting the BEClient.dll. I've tried joining a server remotely however then I just get confirmation of changes, Session lost. I've tried adding DayZ and steam to my firewall. I've DISABLED my firewall. Nothing has worked.
