On friday, I was playing Gears with my friend on xbox live then the game started to lag so I turned it off and signed back in only to find that I can't connect to xbox live. I thought it was just a minor problem from what I've been hearing so I just gave it a few hours. It's been two days now and I still haven't been able to sign in. I hit test connection and it says something about the DNS failed, what do I do?

Playing Ravenholm with only the gravity gun. I came to the part where you have to jump across the roof tops and an endless amount of normal zombies spawn. Lets just say, a fast zombie came at me, two posion ones and a bunch of other ones light on fire. All you could hear was screaming and shouting from the zombies so I just said, "Okay, I draw the line when I've got zombies on fire coming at me and fast ones" so I continued on.

Anytimes. when you decided it was time to continue?
