LaunchAnywhere error, on installation
 

I'm trying to install the latest version of Limewire, with the Blackdown JRE 1.3.1. However, the installer give me the following error message:

An internal LaunchAnywhere application error has occured and this application cannot proceed. (LAX)

Stack Trace:
java.lang.IllegalArgumentException: Malformed \uxxxx encoding.

Does anybody know what's wrong?
