CD Key problems
 

I have MoW and Assault Squad and I can't play mp! I used to play, put it down for a while, and now I want to play again. I'm on a new computer.

When I login with my Gamespy ID I enter my CD key and it says it is already linked to another account. I tried all my Gamespy accounts and nothing works.

I don't know which Gamespy name I used for MoW! Is there a way to find out which name the key is linked to, or a way to reset the key? Thanks!
