Did you configure your firewall so it allows LW full access (advisable not to have 2 active firewalls b/c they can interfere with each other); Firewall configuration instructions (click on link)

Can you give us a total desciption of your set up:
1. What firewalls you have?
2. Connection type? (eg: dialup, broadband, cable, etc.)
3. *** Modem & router brand name & model numbers?
4. Where are you trying to connect from (home, school, work, etc.)?
5. Who is your isp provider (Internet Service Provider)?
6. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up.
7. Is this a your 1st try at LW or is this a new problem with an experienced user.
8. 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?
9. Do you get all red or one green connection bar, etc.? What does it say beside the bars? See example here Connection Bar at bottom left of window sample
