Hi
Did you upgrade your java at the same time U updated L/W if not try it heres
a link.
Now! Go to,
START/Set Program Access/Change or Remove Programs,
now completely remove all versions of java.
Now! Use this Link to get JRE 6 Use the off line installer NOT the (recormended) one,
http://java.sun.com/javase/downloads/index.jsp
Disconnect from internet, close ALL apps n reinstall java.
Follow thease instructions exactly.
You may also need to reset your router to allow L/W access but I cant find
that "Linksys NR041" model to instruct you how.
Do java update first. post back if that hasent fixed it.
Peace.
