Just so you know, because from this it sounds as though you don't, one of the more recent patches enables no-CD play, so you wouldn't need to find that other CD. If you're wanting to play over Battle.net however, you'll still need two separate CD keys. I've not actually looked through the other online options in some time, but I was almost sure there was an option for LAN.. Maybe not though.
No I didn't know that. The last I knew was patch 1.09 and 1.10 was coming out but I never played it. I can't find my disks, so it looks like I will have to buy it again. I can't even find my french disks. Once I find them, I will be back, thanks guys for the help.
