Battlefield 2 Problem

[ghost1552]

Hi,

I am having alot of troubles with my bf2 cd key. This is a completely true story; I have an idiot friend who I later found had stolen many things from my household without me seeing, including money, jewellery, wallets, etc. Aswell, he managed to steal my battlefield 2 cd key booklet. He then proceeded to put some sort of crack on my game, so every time I try to to join a server it gives me an error: Invalid CD Key. I cant uninstall as I will not be able to re-install without having my cd key...so I was wondering how I could possibly retrieve it, or repair my files somehow? I tried patching the game too, but when I go in it tells me its still 1.1 or something on the top right, most likely due to the crack.
Id appreciate any help on this matter.

Thanks.
