Check which version of java you have installed. Open LW and click on Help>About LW, and it'll show the version of LW and Java your using. You should be using Java 6, if not uninstall your current version and d/load the one called (Java Runtime Environment (JRE) 6u1) using the offline installer: Java SE Downloads

You'll also need to allow LW access through your firewall: Firewall configuration instructions (click on link).

Try setting up your router for UPnP, search the faq's here: D-Link TechSupport - Chose Your Country
