Environment: Opening The Launcher

Issue details: Hello, We see each other again, I have installed the latest version of the Mod, I added it to my Modpack (where I deleted everything from the config folder.)
But the problem is when starting the Minecraft Launcher, the Vanilla Fix mod helped me.
Postscript: Do not modify anything of the mod.

Other mods involved: Vanilla Fix, and 51 another mods.

Apologies, this is an error introduced by the spanish handbook translations added in 4.2.9. Should be fixed soon.
