If AgenPro does not start and prints the following stack trace on the console, some incompatibility of the used Look&Feel with the JDK's system color defaults could be the reason.

Exception in thread "main" java.lang.NullPointerException

To get AgenPro to run again, edit the AgenPro3.cf file and remove the line that starts with

LookAndFeel=

or define it as:

LookAndFeel=com.jgoodies.looks.plastic.Plastic3DLookAndFeel
