10. Do this simple test for us. Using your browser go here: http://www3.limewire.com:6346/ The page should say 'Your test worked!'. What happens when you go there? A box pops up saying that the connection was refused.
11. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up. My connection is shared with two other computers in the same room. All connections are fed from the one router.
12. Is this a your 1st try at LW or is this a new problem with an experienced user. First try with LW
13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface? Yes, and it remains there even when I turn off the Windows firewall.

Some additional info that might be of help:

-As far as I know, my router does have uPnP capability, as I'm able to share files on MSN messenger. I think it's true that you need uPnP to be able to do that.
-I had Norton Antivirus 2008 and uninstalled it very recently.

Someone help me please :$
