It could be your Virusscanner Firewall, those things block this "activity" if you dont set them up right, and you should check if you have the correct version of Halo, just to be sure, and offcourse the state of your internet connection, and did it show up at more then 10 games?If so check the list i wrote again, if nothing works, either reinstall or check your internet.
