I recently bought a new computer, and have been thinking about putting Crysis 2 on it, but i've lost the cd code to be able to activate the game, is there any way that i can find the cd activation key somewhere else so i can play again?

It wont be listed anywhere else, but for CD key issues/disputes you'll need to get in contact with EA support here: http://support.ea.com

The above is quicker
