Well if they give better advice, it's your money.

They won't give you much more advice than this probably
User Cant Connect - LimeWire
I do know Belkin devices generally need to be port forwarded. And the usual problem with setting up port forwarding is the very first step (this is where most people make mistakes). If that's not done correctly then the entire process needs to be removed & repeated from scratch. That first step is setting up a static ip address. You will most likely need to reboot the computer after port forwarding.
Setting up a static ip address for Windows XP. (BTW the static ip address should normally be a similar number to the router's address. But instead of eg: 192.168.2.1 which the router uses .. the static ip address should be something like 192.168.2.5 and 192.168.2.6 for next computer on network, etc.)
Also ensure you do NOT have more than one software firewall! All Windows from XP onward have a software firewall. Find the settings for it in the Control panels.

BTW sometimes one version of LW does not run well on particular set ups. So it 'might' be worth trying a different version. Try the 2nd link (
