Also, try a different port to connect through. Try one between 49152 - 65535. A good one to try is 64049. ie: go to LW's menu bar, Tools>Options>Advanced>Firewalls & change both the connection & listening ports. Actually just try changing the listening port initially. If no good, change connection port also.
