i have a windows xp. i click on my limewire icon on my screen and a tiny screen pops up that reads "limewire was unable to set up a port to listen for incoming connections. some features of limewire may not work as expected." i then click "ok". it than claims there is a firewall blocking the connection but i have set it up so it doesnt block limewire, but it still will not allowe me to download anything. this is not always the case, once in a blue moon, it will allow me to DL. what is wrong with my limewire?!
