Hi guys, I broke my ankle today by playing basketball and so I'm gonna stay at home for a while. I thought I would install Warcraft 3 on my pc and play some dota (and other maps which I can't remember now

).
I have the CD-keys (original + expansion) which I bought long time ago, but my problem is that I don't have the CDs anymore, so I can't install the game.
I was wondering if anyone could post a site where I can download the files to install WC3 or if you have any other better idea, please post it.
Thanks in advance.
