I hope I've done everything right to install KUDA shaders and Forge version 1.8 correctly. But it keeps crashing, saying in-game that it's shutting down internal servers whenever I enter a world. 

 

Here is the crash report:

If anyone could help me, that would be great because it really bothers me that I can't play with those shaders. 

If you remove the shader mod, does it still crash? If not, you should probably contact the author of that mod, I would guess something in it is broken, or maybe a version mismatch or something. Can you post the fml-client-latest log?
