OK, I must be a numpty and was not born with the perfect knowledge some of the armchair generals here on this site,never played this game on line and wish to join a clan,and play co operatively,I can always make the cocoa back at base,remember armies fight on their stomachs and some soldiers have bigger stomachs than others.Seriously though,it's difficult to join a game and the only forward seems to be in joining a clan. Someone help me!

Am I stupid? Please help as when I try to join Arma 2 online I receive an message'bad version server rejected connection'. Do I have to join a clan and if I do ,where do I start? Cheers!
