When I Loaded A Shader, It Broke Minecraft

So, When I Tried To Load The Shader After FXAA, The Screen Turned Dead Black. Thats It. It Wouldnt Let Me Do Anything, Just Black.

I Dont Think I Need To Show This But:
1. Load A Save
2. Switch The Shader To Fxaa
3. Unpause
4. Switch It To The Next Shader
5. Bam! Black Screen!
