Hey I have the same problem.
Here are my details:
1. Windows XP
2. Firewalls: Norton and Windows
3. How much ram? 228 MB (I think)
4. Hard Disk space available? I have no clue
5. Connection type? broadband
6. Modem & router brand name & model numbers? BT?
7. Where are you trying to connect from? home
8. What version of Limewire (LW) & Java do you have? (Go to LW's menu Help>About LW...) Will show both LW & Java version. 4.10.9 and 1.5.0_04
9. Who is your ISP provider? BT
10. Are you sharing the connection with other computers or p2p sharing programs? Yes, we're in a wireless network.With 4 computers in the house.
11. 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? Nothing does. Well a new window comes up but nothing is displayed
Thank you
