Another "LW won't connect" thread

[reallybored]

Hi all

System details:

1. Vista Home Premium
2. ZoneAlarm, configured to allow LW access
3. 1GB
4. 46.2GB
All points re. Internet/network connection. I'm connecting to the Internet through a connection to my university network, details available here: Student Network Service
8. LW: 4.14.10; Java: 1.6.0_03
10. Page displays "Your test worked"
12. First attempt at using LW
13. Brick wall is shown
15. AVG, AVG Anti-Spyware, Ad-Aware, Windows Defender
16. UK

Same old story, the ol' non-connection and the "LW is currently connecting to the network. Your search may not return any results until you are fully connected to the network." message.

Any and all help appreciated. Moderately computer-literate, so don't go crazy with the jargon. Many thanks.
