Thanks for replying so quickly. I thought I had given most of the info asked, but now I have more:
1. OS version: Windows XP Service Pack 2
2. Firewalls: Norton Internet Security (allowed LimeWire)
Windows (off)
3. Ram: 256MB
4. HDD space available: 7GB +
5. Connection type: DSL
6. Router: USR 800 or 8000
7. Connecting from: Home
8. LimeWire version: 4.6.0
Java: 1.3.1_03, Java Runtime Environment, and a plain Java that doesn't say (?)

If the browser test didn't work, what does that mean?
I had mentioned a 'jar' thing before - I was referring to the purger.
Thank you.
