Can you give us a total desciption of your set up: 1. What firewalls you have, You have XP & McAffee right? Configure your fireewalls to allow both LW & Java access here: http://www.limewire.com/english/content/firewalls.shtml
3. ram, 4. HDD space available,
5. Connection type,
6. Modem & router brand name & model numbers,
7. Where are you trying to connect from (home, school, work, etc.)?

Do this check for us: Bug Report instructions & sample image
If it says False then your modem will probably need port forwarding to give LW 100% access & not just partial access.
