Access Key question

i just started playing again, after a long time, and i have prophecies, one of my friends has prophecies and eye of the north and is quitting and is giving me his eye of the north access key, one i add that key to my account how do i download the game if at all possible

If your friend has used the key you cannot use it -- even if he really *is* quitting.

You have to buy the game to play it. It's only fair especially since there is no monthly fee.
