nothing happens
 

I've downloaded this program three times... the last time was the beta version, but the same thing happens each time. I have the icon and folder in my applications, but when I double-click on the icon, it appears in the dock for a moment and the nothing. No window. Nothing. Any ideas?

Same thing here- the application won't stay open in the dock. I am running 10.1.5 shared with 9.2 on the HD.
