Key Code lost? Key Code found?

[SandGoose]

Alright, I feel like a dunce right now, but I lost my keycode a while back then I finally got SS, I got the gold edition so that means Im missing 5 races. Is there a not a way to find the registered keycode in my computer because it was installed? Roll with me here a bit...I thought it was called 'Regkey' or something of that sort.

Regkey ;) Close enough.
Okay, to check if your key is still present on your computer, click start and go to Run. Type regedit and go. Navigate to HKEY_LOCAL_MACHINE> SOFTWARE>THQ and check each folder for a file called CD Key.
