Reinstall latest Version of Direct X, just in case something on your system buggered it.
Make sure your Video Drivers are up to date and you have all updates from Microsoft and get the latest Drivers for the rest of your hardware, motherboard, firmware for your HDD and CD drives (Driver conflict may be playing an issue here).. make sure to update your Network Card and flash your modem with latest Firmware..
Configure your Firewall with the ports listed above.. If you have a Firewall and a Router, the kill the firewall,, your router is a Physical firewall already.. you need to configure the ports in it instead.
Now turn your AV back on..
Adjust your INI file for Behind NAT and your vid size and your voices...
