Issues connecting to matchmking

Every time i try to load up any playlist like big team slayer, my xbox looses connection to xbox live. whats the deal here? is anyone else experiencing this? I was literally playing online with friends last night, so it has to be something with this new update that is screwing me over.

bump

no one?

Could a moderator perhaps help me out here and shed some light on what the issue may be

Try restarting your Xbox.

I am also getting this message saying "unable to validate. please make sure you are connected to xbox live and have the war games map pass downloaded

well i fixed the problem. apparently you have to deletethe crimson map pack from your hard drive if you go it for free.
