Ctrl Alt Defeat

At the moment i have no mic,yesterday i was playing on the same server all day,and met up with some German guys (im in the UK),direct chat worked fine. Later a guy in America that i sometimes play with joined the game,and direct chat didnt work,neither of us could see the text,in fact it never has worked while playing with him on several different servers...weird.

Easy fellas.....everyone knows only white folk can be racist...

I have a similar issue, DayZ works just fine,but the Combined OPs single player game is screwed,the armoury seems to work ok,but if i start a scenario it loads and i just get an elevated view of the area with no movement or HUD.Only one of the showcase scenarios actually works,but only 4 vehicles spawn.Campaigns just freeze at loading. I also get the same error mentioned in the title if using the arma2oa.exe so your not alone dude! Im pretty sure its a beta patch issue,but have no idea what to do.
