I too just upgraded to pro and now I can't get the program to launch. It appears to be a java-related error. All other components installed ok, but I found this in the install log:

Install Java LAX file: lax.jar
Status: FATAL ERROR
Additional Notes: FATAL ERROR - Failure to install Java LAX file for LaunchAnywhere: lax.jar

When I try to launch now, I get this message:
Unable to launch java application.
The main class "com/zerog/lax/LAX" could not be loaded.
Either it is not in the classpath or has a static initializer that uses a class not in the classpath.

I hope the last guy is wrong about the OS being corrupted (9.2.2). Does anyone have any clues if there is a simple way to correct this.
