So, I've searched up a lot on the forums, and found this:

Moutain Lion (Which had pretty much the same problem)

If selected: Screen flashes, opens up into a fullscreen mode, then backs out of it and quits
If not selected (Another app is selected): Opens and flashes, then closes.

The previous thread told me to download this java version and then enable it like so.

I have tried that and I am getting the same result. I wish I could continue to play SK! Please help!

Thanks.
