Won't connect anymore....

[JustMeeee]

Hello, please can someone help me, i use Limewire for ages and suddenly it wouldn't work anymore, the world icon has the brick wall in front of it. I have closed or turned off all my firewalls. Occasionally it will work for a short while but soon returns to not working. I upgraded to Pro and it worked at first then stopped again.

1. OS version? (eg: Windows 98) Microsoft XP Professional v.2002 service pack 2.
2. What firewalls you have? Zonealarm (tried to configure to accept all limewire bits and pieces but still didn't work so now have it turned off) AVG anti-spyware (turned off) XP firewall (turned off)
3. How much ram? 320MB
4. Hard Disk space available? 2.76GB
5. Connection type? (eg: dialup, broadband, cable, etc.) Broadband
6. Modem & router brand name & model numbers? Intel(R) 536EP V.92 Modem (Sorry about this but don't even know what a router is?!)
7. Where are you trying to connect from (house, appartment complex, school, student accomodation, work, etc.)? House
8. What version of LimeWire (LW) & Java do you have? (Go to LW's menu Help>About LW...) Will show both LW & Java version. LW Pro 4.12.11 Java 1.5.0_11
9. Who is your ISP provider (Internet Service Provider)? Homecall
10. Do this simple test for us. Using your browser go here: http://www3.limewire.com:6346/ The page should say 'Your test worked!'. What happens when you go there? It works
11. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up. Not that i know of, definitely with no other computers, no other P2Ps that i know of....
12. Is this a your 1st try at LW or is this a new problem with an experienced user. New problem with experienced user
13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface? Yes indeedly

I would really appreiciate any help i can get with this. Also i have tried uninstalling and reinstalling several times, deleting the .limewire folder and turning off tips of the day.

Thanks!
