We figured out a way to have everyone play in a LAN game even over the internet. This allows for a much more stable gaming experience.

Install Hamachi, then join our group "ShadesofGrey" (PW: HAWX).

Go into the Preferences menu in Hamachi and under Presence place checks in Enable, along with two boxes underneath.

You may also need to make you Hamachi adapter your primary adapter. You can do this by going to your "My Network Places" and choosing "Advanced Settings" under the Advanced menu. Select the Hamachi adapter and move it to the top of the list.
