Windows .exe Possible NEI crash

[AlienKnitter]

I set up a small private server for me and my friends using the FTB modpack, and while loving it, we (mostly me, although I do play the most) are running into an annoying crash. I think it's related to NEI, as it only happens when we try to look up recipes, but I am unsure. Log is in the pastebin link, hopefully it helps.

Make sure you're in recipe mode. I am fairly certain it's been reported and is being worked on.

What she said, also make sure that your config files are exactly the same as the servers config files (easiest done by simply copying the servers config files to your client), they are different by default for some reason.
