I have been playing for a short time now and my son liked what he saw, so he purchased DayZ using his steam account. We were going to play with each other so he could get up to speed sooner. The problem we ran into was we could not connect to the same server at the same time. We can play on different servers at the same time but not the same server at the same time and after trying to play on the same server both of the computers are unable launch DayZ without doing a shutdown and restart. What am I doing wrong? Is there some setup thing we have to do? Please help we would like to play together.
