Everlasting search for players.

Hey everyone, I’ve been having some difficulties in matchmaking firefight and campaign.

When I try to play firefight or campaign in matchmaking, it starts to search for players, but it will never find anyone. I’m using a 120g xbox elite. I just got halo reach 2 days ago. I DO have gold membership, and am signed into the right box live account.
I even tried installing and un-installing halo reach to the xbox. Still nothing.

So why will campaign and firefight not find any players? :frowning:
Any help is much appreciated.

-Thanks,
Mrlazy
