I registered, I also downloaded and installed j2re1.4.0, I changed the path and my java -version is now:
java version "1.4.0-rc"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-rc-b91)
Java HotSpot(TM) Client VM (build 1.4.0-rc-b91, mixed mode)

But I still get the same error:
Preparing to install...
Extracting the installation resources from the installer archive...
Configuring the installer for this system's environment...

Launching installer...

Exception in thread "main" java.lang.NoClassDefFoundError: com/zerog/lax/LAX

same error as with j2re1.3.1_02
I have had Limewire working with RedHat 7.1 but it was an older version. New Hard drive , Old Bios meant the Linux partition had to go for a bit but its back, however limewire is not. Please help.
