Lime Wire 2.5 on Mandrake 8.2 PowerPack

Ok, I downloaded LimeWire 2.5 and exicuted the .bin file. This is what I get:

Preparing to install...
Extracting the installation resources from the installer archive...
Configuring the installer for this system's environment...

After these two errors:

Error: Unrecognized JVM specific option `-Xmx50331648'.
Error: Unrecognized JVM specific option `-Xms16777216'.

A small rectangular box with som flashing balls came up, but dissapeared. I assumed that this was supposed to be the installer. What is wrong? (And how do I fix it?)
