The log was too long, so I uploaded it.
Basically, my Modpack had a trouble launching entirely. Once it started to load the stock Resouce Pack, it stops, just STOPs (in other words, close without a crash report). I researched, and checked the end of the log, and found this:
Unable to access any field [languageList, field_74816_c, d] on type net.minecraft.util.StringTranslate
cpw.mods.fml.relauncher.ReflectionHelper$UnableToAccessFieldException: java.lang.NullPointerException
Please, if you know a way to fix this, please notify me.
