Everytime I start my game, it installs it. Is this normal? Is there something I need to do. I've somewhat of a newbie to all this game playing, but didn't think I needed to install everytime I opened the game. Does it override the previous install or is my computer getting multiple copies of the game? Also can I use my keycode on another computer, and is there something I need to do to do this. Thanks in advance to all you skilled experience players. Newbie.
