Minecraft Mods '' Shutting down internal server ''?

Hey guys I have a problem with Minecraft and my mods.

Whenever I hit a mob, the game crashes and there's '' Shutting down internal server ''.

My mods I have are:

Better Dungeons Mod 07/01/10
BiblioCraft Mod 07/01/10
Code Chicken Core 1.7.10-Recommended
CodeChickenLib-1.7.10
CSGO Content Pack 1.7.10
Custom-mob-spawner mod 07/01/10
Custom-NPC-Mod 07/01/10
Damage Indicators Mod 01/07/10
Doggy-Talents Mod 07/01/10
DrZharks MoCreatures Mod v6.3.1
Flan's Mod CSGO Edition V1.0
iChunUtil-4.2.2
Loot Mod 07/01/10
Lucky Block Mod 1.7.10
Lucky Block Rainbow Mod 07/01/10

PokeLucky Mod 07/01/10
TConstruct Mod 07/01/10
Tinkers-Mechworks Mod 07/01/10
Xaeros-Minimap Mod 07/01/10

I tried to delete these options.txt file but that still does not work. Achso and after the shutting down internal server there's a message '' a fatal error has occurred this connection is terminated ''

Something went wrong because there are so many mods all at once, it can be that some files do not "tolerate"
