I've been trying for months on and off trying to get limewire to work with no luck. It had worked previously a few months back for a long time before that. Then one day it stopped working. I've done everything. Did port test, that worked it said, did port forwording, did firewall config, did the delete the limewire directory, my isp isnt blocking it according to them, the program Ares works on my computer no matter what port i use on that. limewire wont work on any port, my router is using upnp and it is activated, limewire shows a brick wall no matter if my windows firewall is on or off. I dont know what's blocking it. My router has no firewall that i know of, or read of. The thing is, why would it just stop working one day, when it worked flawlessly before? someone please help

i have:

Windows XP SP2
No other firewalls other than windows
Wireless Internet (Netpoint Communications)
Linksys Router BEFSR41 v2
newest Limewire version (4.12.3)
connect at home, 2 computers on router
latest Java
