Ok, sorry guys but i've put up with this for a full week now. And, I give up. Can someone please link me to where i can request a refund? If that's not to hard. Thank you.

It was fun while it lasted. I got to level 8. Now when i try to log in it tells me to enter a registration code. so when i enter it, it tells me that its already been used. I don't feel like figuring out this problem. I've already solved enough problems just to try to play this game and I give up now. I just want my money back.
