I finally connected to Limewire, but the 'search' button won't work - like, it's gray/is grayed over, i can't click it. i'm on an ethernet network, does that have something to do with it?

--i just realized that in the bottom left corner next to the red button it says that it's sharing 1 file, but in the limewire titlebar it says "disconnected / no files available" AND the search button won't work. is it connected or what?!

help would be MUCH appreciated-
