Help! :(

I just tried logging and it is asking me for a registration code?! I've already registered and have been playing fine - now it is asking me to either set up an account or register. I tried re-registering and it says the code has already been used (which makes sense obv). WTF is going on?! Is this happening to anyone else? Can't log in now :(

If you bought the game through download, check your spam box. The final confirmation code they ask for was in my spam box in my email.

I FOUND IT. I just had a heart attack. :D
