Great looking database tool with glowing reviews. Unfortunately, I can't get it to install.

I've tried installing both v4.0.4 and v4.1 on three separate Macs (OSX 10.2.8 with all Security Updates) first with Java Framework v1.3.1 and then upgrading to v1.4.1 and kept getting the following error dialog box:

• Installer UI Mode Error:
  Installer User Interface Mode Not Supported
  Unable to load and to prepare the installer in GUI mode.

followed by

• Fatal Application Error:
  This Application has Unexpectedly Quit
  Invocation of this Java Application has caused an InvocationTargetException. This application will now exit. (LAX)

and a bunch of java.lang.NullPointerException locations.

I've tried repairing permissions and re-prebinding with no change in results.

I could really use this tool on a current project, so don't make me go to a Windoze box! Please! ;)
