Hello.

Ia have the same problem.
Currently have lime wire 4.16.6
Mac OS X 10.5.2

I've searched all over the forum and seen suggestions for MacOSX 10.4.... but the firewall setting have changed in 10.5...

1) I did have them on before... but now I turned them of by going to:
System Preferences > Security > Firewall

I'm using the radio button for Allow all incoming connections

In Limewire I get the brick wall icons (meaning it detects a firewall)

I've also tried replacing the gnutella.net file

LimeWire Forums

But still no luck....

Anything else I should try?

Thanks alll,
