I have been using Limewire for a pretty long time now, but recently (within the last week or so) it has not been working right. Now every time i open Limewire I get an error message saying "LimeWire was unable to set up a port to listen for incoming connections. Some features of LimeWire may not work as expected." I tried some of the common fixes that people recommend here, but it hasn't changed anything. Any ideas on what could be wrong?

thanks
