Although not a big deal, I cannot get the Live Messenger thing in my Xbox to work. It keeps saying it can't sign-in. I have the proper ports open on my router and iMac (I'm using my iMac as a bridge), but still no results. Any idea what's up? Oddly, both of my Macs were having trouble logging into MSN Messenger lately, but they seemed to be working now after opening up the proper ports. It kept hanging at sign in for some reason.
