Darkys Key Changer Help

Hey, i got my own key-stealer and i wanted to test how fast it gets the keys once somebody has used it so i clicked on it and let it take my key thinking i could just get it from the database and use Darkys key changer to change it back. When i try to open Darkys key changer i get the error: Failed to read Hex-Key from registry! Error code: 0. I am assuming this is because i don't have a hex-key because the stealer took it. How can i change my key back to the original? I heard you could use steam but it doesn't seem to change it :|. Any help would be appreciated.

Thanks.

Edit: if you help i will give you a CD key.

It looks like your key stealer fucked up your registry...There is a sticky on how to fix that. If it doesn't work, then you'll be looking to reformat
