I know what I need to do I just cant figure out why when I try and run Reqtificator the screen pops up for literally half a second and then colses.

So I've been trying to get Requiem to work for an hour and finally figured out what I needed to do, but now I need to run the Reqtificator. But Java just flashes a screen and immediately closes why does it do that, and how can I fix it?
