I second this, happened to me also. I was shot dead at NWAF (probably you, you horrible person!!) then about 10 mins later I was teleported into the sky and fell to my death. Been having BattleEye problems with US171 since. "script restriction #55"
I had a problem with all servers having little red x's next to them when I first tried to install DayZ. I updated to the latest version of the DayZ files through the 6 installer which fixed it for me. But seeing as you can't get the 6 installer to work, maybe try downloading the latest files from the dayzmod website?
