So when ever I launch Dayz I get the error message 'addon 'ca_communityconfigurationproject_e' requires addon 'AWeapons_E_M252_81mm_Mortar' and when I try to load into a server it takes me back to the arma 2 OA main menu, Where the player options are, So could anyone help out with this? This is Dayz mod not standalone
