Hi,

It would seem I am having a similar problem. I am running Mac OS 10.4.9 on a Core Duo MacBook with the current 1.5 version of Java and do have my preferences set as mentioned above. When I try to launch Limewire it stops with a dialog box that says "fatal error". Then gives me this text:

LimeWire version 4.13.2
Java version 1.5.0_07 from Apple Computer, Inc.
Mac OS X v. 10.4.9 on i386
Free/total memory: 16297016/19791872

FATAL ERROR!
