Modded Minecraft Keeps Crashing After One Use

[CowboyEthan]

My friends and I are playing on a hamachi custom modpack server and I am hosting. My Minecraft worked smoothly on the first day. It's the day after and now I can't open my minecraft, it crashes every time right after forge finishes loading. Any help PLEASE ;3;? Note: we're using Curse to make the custom modpack.

 

EDIT: here's the crash report

1) You have posted in teh wrong section.  This board is for people who write mods. You want the Support & Bug reports section.

2) Your error is in Chisels and Bits, so go bitch at them, not Forge.

Locking, this issue does not appear to be Forge related.
