You possibly have a mod somewhere in your mods/coremods folder that is for a different version of minecraft than 1.8.9

edit:
In-fact yeah, the part of forge that the problem-causing mod is trying to find:

ClassNotFoundException: cpw.mods.fml.relauncher.IFMLLoadingPlugin

has been moved as-of 23rd September 2014, so it must a mod predating this change:

You could alternatively try this in-development installer:

It basically automates the manual installation process, but makes sure to keep everything separate from your existing profiles/modpacks/installations so you don’t run into issues like this.

padrao1796 · 29 June 2016 22:49

yay it worked! thanks a lot dags really aooreciate it?
just a question now I can installother mods like betterfoliage and voxel map right? as long as they are 1.8.9. of course

dags · 29 June 2016 22:57

Yep, you can can add whatever mods you like, providing they’re compatible.
If you used the installer, the place to put your mods is:
.minecraft/profiles/ardacraft-1.8.9-0.7/mods/1.8.9/
