Hi mick360,
Your version of LW doesn't have a firewall indicator. In LW go tools > options > bug reports > view example. Scroll down to 'recieved incoming this session'...is it true or false? If it's false, you can't recieve incoming connections from other computers & there's probably a firewall problem.
First thing to try: Delete LW's preferences folder when LW's properly closed. the preferences folder is located in C:\Documents and Settings\your username\.limewire
This will kill 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.
Also make sure that you have LW set to connect when the application starts...tools > options > connections. Make sure 'connect on startup' is ticked.
Make sure that the XP firewall's configured to allow LW.

Next, try installing this version of Java. Use the JRE offline installer & remove your current Java version before you install this one.

Have you tried connecting with a later version of LW? The latest stable release is 4.12.15 & the latest Beta version is 4.13.13. You can download either version at the official site here.

If you don't have the 4.8.1 installer saved, you'll lose that version if you install another version of LW.
I can't find any much info about your modem (the Next G network is a bit of a mystery to me...I'm not a Telstra customer), so I'm not sure whether yours has an internal firewall. I'm guessing not. You could always call BigPond & ask whether there's an internal firewall & if so, how to port forward for your modem.
Damn...I'm too slow
