I know this is a common problem for alot of people but ill explain what my specs are. I have Windows XP Service 2. it has a firewall. I even disabled it, put in the ports under the exceptions and even restarted the PC and it still doing the same thing. I have a modem which is cable and I dont have a router. it is conntected to one computer. I called Microsoft, they told me to call RoadRunner. I called RR and they said that they do not support those port numbers. assistance wouldbe appreciated. the game playing on multiplayer did work on service pack 2 the last time I played it.
