Limewire does not connect. Help Please!

[Ray-A]

Hi all,

when I open Limewire it will not connect. My system is as follows:

OS: Windows Vista 64 bit
Firewall: Norton Internet Security 2007
Ram: 4GB
Hard disc space: about 300GB
Connection: Broadband Cable
Modem: Motorola
Router: Netgear WGR614v7
Connecting from house
Limewire 4.8.1
Java 6.0_0.2
ISP: Virgin
Test: Your Test Worked
A laptop is also connected to the router
I have previously used Limewire with Windows XP
I do not see a brickwall in front of the globe
Router is set to UPnp enabled
I am in the UK

After looking at the posts here I tried changing the port number in Norton Firewall but it made no difference. I have also looked for the Limewire folder in AppData but there is no folder there.
Can anyone please help me set up Limewire. I am not very computer literate so step by step would be a great help.
If anyone can help me please.
