I too am having problems downloading, I have great connection but it says it is firewalled and I tried to go through my Windows XP network firewalls and added the LimeWire port, but it still is not working. I do have wireless, so is it potentially an issue with that? My roomie's computer has the router. We have Netgear. I have Windows XP and LimeWire 4.9.37. I've tried going through all of my network connections and adding the port, which it seems to do successfuly, though, whenever I go back to check it, it has changed the IP address you are supposed to enter (127.0.0.1)
