Don't use 2 software firewalls at once. Choose 1, configure it to allow LW & turn the other one off.

In LW tools > options > advanced > firewall config. Change LW's listening port to something in the range of 49152 - 65535 (eg 65000) > apply > ok.

When you reinstalled your Java, did you remove any other Java versions before installing the new one?

If you can find your router model in the list here, try port forwarding.
PortForward.com - Free Help Setting up Your Router or Firewall
Click on your router model & then choose LimeWire from the list of programs. Then you'll see step-by-step instructions for port forwarding.

If setting up a static IP is part of the instructions, don't miss that step. LW's listening port, port in the 'manual port forward' box & port forwarded within the router setup should all be the same number
