I have downloaded the Arma 2 demo and I install it successfully. However, when I go to start the game either by the shortcut, start menu or in the game folder I get an error message. It says the X3DAudio1_6.dll file cannot be found and reinstalling the game may resolve this issue. I have installed it 3 times and it still comes up with this message and won't load the game. Help!
