Me and my whole Clan (20 Members) get this Error on starting up the Game at Main Menue. We aren´t able to Preview any Mission at the Missionseditor and also not to play any Map on any Server. We tried to disable everything, and nothing happened, we reinstalled Arma and again nothing happends.
The Problem exists since the 11.07.2013 v0.72 Updatepatch. {F20803}
