My payed DLC has been removed

So I bought the Crimson Map Pack first day of release and everything was going well until today when I got on Halo 4 that I got a message saying I should probably download the map pack. I can’t be the only one experiencing this. I will re-download it later but that’s not the issue. The issue is that 343 decides to not update a brand new game for a month and a half and than they pull this crap. Is anybody else experiencing this problem and will re-downloading the DLC fix the problem?

My friend is saying he has been getting the same message but he got the map pack for free. I did not however (I bought the LE of Halo 4) and I’m getting this message.
