Java error when starting Maltego CE 2.0

Hi, I get 2 exceptions whenever I start Maltego and when I try to go into Manage Transforms. Please note that this not crashes it. This is a Windows XP SP2 machine with Java version:

java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing)

This is the exception I get when I start Maltego:

java.lang.NoClassDefFoundError: javax/swing/GroupLayout$Group

This is the one I get when I try to go into Manage Transforms:
