Is there anything specific I need to do to set up multiplayer? I try to play it with the open SCP, I don't see any servers. Does no one play this game? I doubt that because people play Allegiance after all (that's essentially the same thing, only more needlessly complex). I haven't played a game yet where my router just blocks the master server. A very interesting thing to note is that I tried to go to the PXO website and get an account, but when I click "submit" it gives me a 404 error.
EDIT: Oh. Yeah. I have SCP installed and running fine, that doesn't seem to help (there are still no servers on the list).
