GLSL Shaders Mod for Minecraft keeps crashing?

Surgery is the best option for you. I would not stress it out tho. When it is done, you will feel like new!

What graphics card do you have?

invalid operation at final worldtime usually happens when your hardware can't handle the shaders. It does say it needs recent graphics cards to run the shader, if you don't meet the requirement then you won't be able to run it.

Every time i go into my game and click a shader pack it crashes
