I still get the "registration failed: ssl connect error (schannel:failed to setup extended errors)" I have had this error for the past few patches. I have the same issues of being able to play normal arma 2 games but if I try and play DayZ I will see the error and get kicked from the server either immediatly or a few minutes later. I am currently running the Arma 2 patch: 102591 and the DayZ patch 1.7.6.1, I have had this problem for the last few patches now and really would love a solution.
