Hi, so I was installing some mods. And everything was going fine, I install each mod and then check minecraft, change what I need in the config, and repeat, so that I can see where something goes wrong.
Amongst other mods I have Thermal Foundation, ProjectRED, Mekanism and VoltzEngine. What these four have in common is that they produce the same ores, so I decided to only leave on the Thermal Foundation ones.
With ProjectRED and Mekanism I disabled the oregen without any trouble, I even generated a new world. The problem is with VoltzEngine, after I change it Minecraft opens normally, but when I try to open or create a world, it just returns me to the main menu, and if I change the VoltzEngine oregen to default it works normally again.
This is the FML log: http://paste.ee/p/oKGTQ#
Any help would be greatly appreciated and thanks in advance.
