Correct, a couple of files slipped into the client build, removing worlds_test_ce.pbo and worlds_test_ce.bisign will fix the connection issue. These files are located in the addon directory, in the install of the experimental client. Here how to find the file
From the Steam library, right click on DayZ Experimental >> Properties,
Go to the "Local Files" tab and click "Browse Local Files",
Navigate to the Addons folder and deleted the two files.
