My boyfriend and I just bought and downloaded two copies of EMpire Earth 3 from CoG.com and we are unable to LAN play because it says "CD key already in use" any help?
You'll have to contact support about that.

http://www.gog.com/support

Select the game from there. In the lower right there's a "I can't find a solution" option. Choose that and fill in the form.

Good luck!

Like Navagon said, the game comes with a generic key and you need to contact support to get a key that actually works. Here is the link for multiplayer key requests:

Edit: Nevermind my link. Use the one Navagon posted.
