I'm having problems connecting with Limewire

I started with Limewire 4.9 added http://www.limewire.com/english/content/firewalls.shtml even though I have firewall disabled
tried removing .limewire with no instance of LW running. It still didn't work. Then I installed 4.8.1 and tried the above again and didn't work either.
http://www3.limewire.com:6346/ doesn't work
K-Lite Pro does not work either
Azureues BitTorrent works fine

1. OS version? XP Pro SP2
2. What firewalls you have? XP Firewall disabled, & some sort of campus firewall
3. How much ram? 512MB
4. Hard Disk space available? 2GB
5. Connection type? LAN off a T3
6. Modem & router brand name & model numbers? N/A
7. Where are you trying to connect from? campus
8. What version of Limewire (LW) & Java do you have? 4.8.1 w/ 1.5.0_02
9. Who is your isp provider? N/A
10. Is this a your 1st try at LW or is this a new problem with an experienced user? I've tried LW on campus at least a year ago and it worked.

Any help would be greatly appreciated.
Thanks.
