It looks as though something is blocking LimeWire from connecting. This usually caused by a firewall. Check out this link for configuring most common firewalls. http://www.limewire.com/english/content/firewalls.shtml

This may also be caused by a NAT firewall built into your modem/router.

If this doesn't help please post back with more information.
