Problem with JXTA configurator

Hello there
I'm having some issues with JXTA on my windows machine.
I'm writting a simple shared file editor with JXTA and all was going
fine while i was working on a OS X enviroment. But now i've to work on
a windows machine and when i try to run my aplication the configurator
shows up, but i get the configurator screen with a white background
and i can't enter/click anything.
All was wokring normal on the OS X. So i dunno what is the problem.
I've already included all jar's that come with the lib into my
classpath to no vail.

If that matters: jxta for j2se 2.3.4, Windows XP, Java 5.0 update4

Thanks a lot for any help!
