Try resetting your computer, usually solves the problem. Also be sure to disable any firewalls you have.
What's wrong with you.You can unblock certain ports on your firewall, but you SHOULDN'T just turn off your firewall.
Honestly I don't see why firewalls exist in the first place. Unless an application is vulnerable to attack and is running on your computer; there's no risk.
