I just looked up your order using your email address and it is settled. You can download your game here: http://www.telltalegames.com/download/cultureshock
To activate it, click "I've already purchased this" on the first game screen and enter your order number and the password you created when you ordered. I will send you the order number in a PM.
What size shirt did you order?
EDIT: By the way, our system shows that you were sent an order confirmation on 11/8, which is when the payment went through. You didn't receive it?
