I just double-checked that my G5 iMac with OS X 10.4.2 is up to date as of half an hour ago. LW 4.9.23 runs fine for me.
What kind of machine are you running?
What do you mean by "LimeWire doesn't work"? Does LimeWire crash before showing the startup screen? Does LimeWire show the startup screen and then crash? Does LimeWire continue to run without being able to connect to the Internet?
Have you tried changing the JavaApplicationStub that LW uses?
