Thanks for all the replies. I have the retail disc. Like I said in the second post it works fine provided I use the link I mentioned. Is the configuration tool any good ie is it worthwhile having? I just wanted to play the game is all... And what with all the extra content?
Off topic: I know I should probably update my system but at the same time I can't be bothered...
Btw: is this a role-playing game? Never played anything like this before. I like.
