So I do think I have them, as I can see each Specialization on the list. But they are still locked. Is this just the way it is? If I still need to get to SR50 to unlock them, why did they advertise it as "Launch Day Access," implying that you could use the specializations right from the get-go?

So I bought the Limited Edition Halo 4, and went online to find out that an email with an unlock code will be sent to the email associated with the Xbox live account to access the specializations. Problem is, when I originally subscribed to XBL, I was using a different email (the one my cable company game me). Is there any way I can change the address this unlock code email goes to? Anybody there at 343 able to help me out with this? I really don't want to miss out on content I shelled out the extra money for, especially if people who even bought the standard edition will at least get something while I get nothing.
