Hello

You haven't said what your problem is or anything else. I'll guess it's a connection problem.
Did you configure your firewall so it allows LW full access (advisable not to have 2 active firewalls b/c they can interfere with each other);
Firewall configuration instructions (click on link)
I can't say any more than that because I don't know whether you're using windows or linux or mac or ... & which version of Java you're using or that type of connection or what brand & model of modem/router, etc.
