Hello. So i got Arma 2 Combined ops. downloading and its almost down so i need to ask, How should i install it? manually? or Dayz Commander? I heard about Commander updating then messing up the game to where they can no longer play the game and other issues, and about installing it manually i have no clue :L I am leaning on Commander but has anyone else had any issues with it? ect.
