I went to the link you provided and tried everything with no success. I did have one issue when I tried to reinstall the java update as a standalone. I got a error message saying that I could not install on the selected volume beside my java was already up to date.
I guess at this point I guess I'll just have to wait for a new version of LimeWire, I wonder when do you think that will happen? Maybe even an update to 10.4.3 will help whenever that may be.
