I think i broke kitten launcher after 10 minutes lmfao.

I don't know what to do?

It automatically set up on experimental which i didnt realize, so i made a world, then i saw that the character wasn't bound by points which honestly isn't really something i'm into. So i set the launcher to the latest stable and now the game just isn't launching? anyone got knowledge? Or do i need to download something to play the stable?
