Hi!

Well, today i started MInecraft and this appeared, and I find it pretty weird because yesterday I played and everything was alright.
Oh! And just so you can know, I installed again all my mods but the error is still there, and if i play the vainilla MInecraft or Minecraft with my mods it work, unless i put Mo' Creatures.
I don't know if this if userful but these are my mods:
-Too Many Items
-Mo Creatures
-Twilight Forest
-Forge
-Custom Mod Spawner
And i also have some texture packs.


The error:

I hope you can help me, and sorry for my bad english

I had what appears to be the same error, StringIndexOutOfBoundsException in mocreatures.
Would appreciate thoughts on how to resolve this issue.
