Don't run 2 software firewalls together, they'll interfere with each other! Turn off the Windows firewall & configure the Norton to allow LW. You could also try removing all the LW rules from Norton & then adding them again.

Next, delete LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).

This will change all of your settings within options, you'll have to go back through afterwards & reset things. If you're not sure of your settings, go through LW's tools > options & write them all down, so that you can reset things later.

You could try this older version of Java, just to see whether that makes any difference: Archive: Download Java 2 Platform Standard Edition (J2SE) 5.0 Update 11
If it turns out that Java's not an issue, it's easy enough to re-download the latest version
Download the JRE offline installer & remove any other Java versions before installing another one.
