I am having the same issue on my Intel Mac. I am unsure as to when LimeWire "broke". I was running some older version [ 4.10 I believe] and now it will not launch. I am running 10.4.7, Quicktime 7.1.x . I have re-run the Java installer as recommended.

[JavaAppLauncher] application launched with ppc-thin application stub. Using native application stub instead.
