Was pleasantly surprised by your immediate response but I may not be able to reply to you immediately. Please bear with me.

Before you could reply I also tried out this step suggested by a helpful forum member.
I deleted this key in the registry.

My Computer\HKEY_CURRENT_USER\Software\Microsoft\Wind
ows\ShellNoRoam\MUICache

C:\Progra~1\LimeWire\LimeWire.exe

But.....

Coming to your advice:

After LW was open for about 30 mins., LW stopped working. It gave an error message saying firewall or ISP may be culprit.

So I again restarted LW and immediately did the test you recommended the test: Bug Report instructions & sample image. It is False.

My connection type is Cablenet.

I don’t have a modem or a router at my home but I did trace the cable to a NWay SWITCH (PRONETTM 8-P) at the top of our building.

About Java 1.5, my machine was already up to date but still reinstalled Java 1.5 from the link you provided.

Did check my firewall settings within LW: Tools>Options>Advanced>Firewalls & “Use UPnP” was already selected.
