Jeez you're up early! Either that or...

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. Do you have SP2 installed?

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

Sorry what Von Deimon state was that?
