I'm new to PCMC but managed to get a few hours of gaming and some mods with no problems. Then I decided to see how a shaders mod would work. I used GLSL. It crashed the game and now everytime I load MC it gets stuck on the brown loading screen. The error log report identifies the crash as Code 1 and sometimes the loading screen shows 0%, especially after loading a superflat.

I reinstalled MC 1.11.2 again and that did not fix the problem.
I deleted all MC files and folders. That did not work.
I deleted the latest version of JAVA and reinstalled. That did not work.
I deleted again all MC related stuff including Forge. I reinstalled only MC without Forge. That did not work.

I do not think that my NVidia card is creating this issue as the game worked before I installed the shaders mod. I have not yet reverted back to the IntelGraphics as yet.

I have no allocated any memory or anything like that. I have not deleted items from the computer's Registry.
