Help!

So I bought (pre-purchased) the retail version and I have been using the beta key since then, and I got the game box and new CD key when it came it like on Tuesday. It says you need to add it to your account before 5 days, but I don't know how to. Does anyone know else know how to?

Thanks, but it doesn't say where to actually put the code in.
