Hi tried all the stuff that this forum has suggested, and it all works, untill it dosen't. Nothing seems to stick.
I using XP i have the SP2 thingy and i have LW 4.2.3. I wish that there was a quick fix or some thing.

Can you give us some more details as to your setup?
1. Where are you connecting from (home, school, work, etc.)?
2. What is your modem-router brand name & model number?
3. What Firewalls do you have?

A. You are using XP so have you configured your firewall(s) for LW & Java to have full access: http://www.limewire.com/english/content/firewalls.shtml

B. Update your Java: Java 1.4.2 (click on link)

C. Update your LW to 4.2.5: http://www.limewire.com/english/content/download.shtml

Have you searched the forum for SP2? There's both M$ & 3rd party patches for SP2 as well as other solutions. (We don't recommend people updating to SP2 unless they run a business or have a major network. SP2's not for the home user.) SP2 reduces connectivity & sers firewall to their default.
