I found the thing to change it. But it doesn't let me. Like, it says "choose which one to open this with". I chose Toribash.exe. It won't let me check mark the box to always use it. I click on Toribash.exe, but it only opens the game, and not the replay with the game.

It won't stop opening with Adobe PDF thing. And when I delete Adobe, it still opens it in it. Says "this file is not compatable with Adobe". So I can't watch it.
