Resolved Minecraft isn't working?

Hello, I've been using 360revolution a bit before the update, and now I'm having a problem with Minecraft.

When I open minecraft I get this error:

I click continue and think nothing of it, but when I open my save file (which was extracted from Horizon) It pops up this error:

So I decide to click continue, and it does nothing, it doesn't show my inventory or anything. I've tried getting saves from other games and they seem to be working with 360revolution.

I do have the recommended net framework, I just don't know what's causing this problem. I've also tried redownloading 360revolution, and nothing has been working.
