I got Power PC G4 Mac OSX Tigr 10.4.2 SSL and bought LimeWire Pro.

It worked for a while and recently immediatly crash at start up when it gets turbo speed.

I reinstall several times LimeWire
I removed firewall and added Gnutella 6346-6346 as TCP and UDP

I tried to reinstall java 142 but my mac refuses answering that it is already installed:I still get from Installer that "this volume does not contain any Java version that needs to be updated"

I tried the move kmag proposed

Then re-install your Java. Get this Java http://www.apple.com/downloads/macos...update142.html & if it refuses to reinstall, go to your Receipts folder & remove the Java142Update2.pkg from the receipts folder.
ie: go to OSX folder>Library>Receipts
Then try installing it again. This is generally the fix for your problem. See sample image of where to find here: Where to find Receipts folder (click on link)
