Is there anyway to download the client?

Well there is one obvious way, but is there any way to download the client in a proper way so to speak? Because I have my code, payed and done for, but I don't have the CD. Usually steam lets you download the client of games you have but it's not on there. Is there any way to add the code, have them verify that it's a real one and then download the client or is it essential to have the CD for the first time?

Any help is appriciated.

Hmm not to sure on the downloading side but you could borrow the cd version from a friend and install that via steam and enter your legitimate code. Don't think SI would have any problems with that.

If you use the Activate a product on Steam option in Steam you should be able to enter your key and then have Steam download the game.
