All of the menu buttons except the exit button of CW3 are not working. Please Help.
You're going to have to give us more information. When did it happen, and what were you doing to trigger it? Is it a problem immediately on the title screen as soon as you launch the game, or do certain actions cause it?
One thing that comes to my mind is that sometimes the game's resolution will mess up, causing inputs to not correspond to where the game actually is. If the game's window is not in the center of the screen, try maximizing it.
