That means it isn't connected to any hosts. When you installed LW, did your firewall ask if you want to block/temp. allow/perm. allow LW? If so, what did you click? You need to make sure in your firewall settings that it is allowing limewire to connect w/ your computer. Also, look at the 4 bars at the bottom of the limewire screen. If they are red, you aren't connected, if they are green, you are and you should be able to search.
