It's probably throwing an error you're not seeing and the window is closing on you.

Try this:

Change the contents of arbaro.bat from this:

java -jar arbaro_gui.jar

to this:

java -jar arbaro_gui.jar
pause

This will allow you to see what's happening and perhaps offer a clue as to why the program isn't loading.

If you can post back the contents of this, maybe we can help. Hopefully it's not an issue where it doesn't like the 1.5 JRE...
