How long does it take to get a registration code?

I ordered 3 days ago and my payment cleared today..but i haven't gotten any emails from anyone about a registration code or anything.. and when i go to "ive lost my code/need my code" and i enter my email it tells me that there is no email address associated with a registration code and that i need to order to receive one..which i did!! so whats going on?? can someone tell me how the whole process works after you order..thanks.
