No clue but you will need to provide a bit more detail like: where did you download Limewire from & what java version you have installed, what OS you have and your system specs please? and, make sure you are connected fully to the internet while downloading from Limewire. Also, you might want to browse the forum stickys for they have lots of useful info in them.

On the licence thing, you might want to turn that off, not on, for downloading or else you won't be able to dl much from Gnutella.
