I didn't know where to post this, so...

Me and 2 others play a private modpack which I created personally and have been for a while.
Recently however one of us now seems to get disconnected from the server every time they interact with anything, whilst the other two are still fine.

She gets the error ' A fatal error has occurred, this connection is terminated'.

I have tried a fresh install of all mods, giving her my whole FTB folder, playing it on vanilla minecraft launcher, and deleting the player.dat file, none of which have worked.

Any suggestions?
 
Edit - we have discovered that the mod causing the problems is NEI..

Still don't know how to fix this however
