Heyho

My problem is that my pc is totally damaged, i tried to fix a problem but instead of fixing it, I made everything even worse.So now i have to set up my system completely new and right now im saving my files which i want to keep.

I want to keep my cod4 cd key(i have entered it when i installed cod4 but now its gone .. means i dont have written it down somewhere and the cd-case with the user's manual and the cd key ... disappeared ) but i cant view it in the multiplayer options, because i cant start the game ( you remeber ? "pc totally damaged" )
I hope that there is a way to view it from any file in the installation folder? I mean: it has to be saved somewhere?
well i really hope that there is a way to do this if it's impossible pls don't laugh at me

sorry for my miserable english(i am in a hurry) and if there's already a topic like this pls tell me

The only place that I know that the cd-key is located is in the registry under HKEY_LOCAL_MACHINE - Software-Activision-CoDkey
