my limewire will not connect
 

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?!

You haven't indicated anything about where you are trying to run limewire from, home, work or school. It makes a difference because although you might not have a firewall on your computer doesn't mean that their isn't one some place else on the network.
