Well I've found out one piece of news here: http://forums.whirlpool.net.au/forum...?t=181659&p=-1 that your modem has no NAT/port forwarding ability. Just to make it easier for you: Bug Report instructions & sample image (click on link) If your result is False, then you probably haven't configured your Firewall properly to allow Limewire (LW) full access. Check your XP firewall (& any other firewall you may have) HERE (Firewall configuration for LW)

If your result is True, then we'll need to rethink the cause of your problem.
1. Did you update your Java?
2. Have you tried deleting your LW Preferences folder found here: C:/Documents And Settings/your_username/.limewire And delete the folder called .limewire
Before you do this make a note of your LW settings, b/c once you delete your preferences you'll need to reset them.
