Limewire/Frostwire FATAL ERRORS

[jamesfareham]

Hi there people, I have been using Limewire on my mac for ages, but today I upgraded to the newest one and after a seemingly successful install a window pops up telling me that limewire has encountered an internal fatal error etc...There was a 'Review' button which i pressed which opened the following diagnosis (Which I don't understand in the slightest!) I have uninstalled, deleted and redownloaded countless times and also tried frostwire but the same thing keeps happening! Any help at all would be really appreciated!

LimeWire version 4.10.5
Java version 1.4.2_09 from Apple Computer, Inc.
Mac OS X v. 10.4.4 on ppc
Free/total memory: 17479008/19726336

FATAL ERROR!
