Cool! So their support is in that link.

But first, If you could, as last resort, try to do a factory rest on your console and then try again, but, the downside of this procedure is that you would have to download it all again to your console. :/

In that case mate, have you try to report this issue to Activision, to see if they know something about it?

That's odd. How long has it been like this?
