No Access to Support Website With Correct Email

I received an invitation to flight 3. I am unable to follow the links in my email as it keeps saying access denied to the official Halo Support Site.

I dont know why this is happening since I am literally clicking the link from the registered email.

Is that email address different from the address you use to sign into your Xbox Live account?
If it is, that’s likely the problem; you need to use your Xbox Live info to log in (like you’ve done to log into this site) which might be different from the verified email address that received the flight invitation.
If it logs in automatically try opening the links in a private browser window and log in manually.

Will report back when the servers go-live and ill try again. Still cant access the website.
