GUI's cause crash.

[Trending_Insane]

I'm capable to play the game but anytime i try to open any GUI's the game crashes.
I'm playing on Direwolf20 modpack.



The Crash report is attached.
Any advice would be great.

If it's crashing when opening GUI's then I would bet on NEI.
But I will let others with more skill at reading crash reports comment.

Yep, looks like NEI, or a mod using its API.

Try redownloading the mod pack, this isn't a normal error.
Also, it may be a long shot, but is the Minecraft window smaller than default?
