Just a quick question...did you start the game server (Host), or did you connect to one on the net? If you are not hosting the game server, it is possible the host stopped hosting, therfore you cannot find it.
Yes I did. The two of us are connected to just one router as we both use it for internet purposes and I am the one to host the game. After some time, I told my sister to host the game just to see if it would work, but alas, it just won't. We already tried uninstalling the game and deleting every file related to it, and after installing it again, it still won't work. Sigh~ I'm really at a loss here.
