We have McAfee free with Comcast and in order for it to actually let me play some games I had to change the settings on the firewall a bit. I did and actually set a tighter security level. Everything worked fine earlier today, but now I can't send or receive anything in Outlook Express, connect to Windows Live Messenger, or connect to Xfire. We're switching to AT&T tomorrow. Is there any way to fix this, or did the stupid firewall block us from those things? I tried turning off the firewall and connecting, but no luck.
