Hi, sounds like what I have been getting. Only my problem is this: Limewire kept opening on it's own after I closed it. So I uninstalled, now it still keeps trying to open then I get this message, obviously because the program is no longer there.

LimeWire version 4.18.8
Java version 1.6.0_05 from Sun Microsystems Inc.
Windows XP v. 5.1 on x86
Free/total memory: 31356560/33357824
com.limegroup.gnutella.gui.GUILoader$StartupFailed Exception: .\lib\hashes (The system cannot find the file specified)
