The same thing happened to me amongst many other issues associated with Modern Warfare Remastered. I bought the digital download so I contact Microsoft and they gave me a refund. If you can't play the game why should they keep your money? My NAT was open on my console and COD Modern Warfare Remastered showed my NAT as open as well but I consistently got the same error code!
Two days I can't play still getting different error codes taking my disc back for a refund
