Problem with nei causing me to be kicked from my server.

I just downloaded tekkit and the launcher today and I was trying to get it up and running but seconds after I join I get an internal server error.

The server says the problem is :

[WARNING] Failed to handle packet: java.lang.NullPointerException

java.lang.NullPointerException

does anyone know of a fix for this?

Reinstall you Tekkit client (NEI save slots and settings are stored on client side) and if that doesnt work then perhaps delete root/worldname/players/yourname.dat on the serverside to wipe your inventory and remove possible corruption there.

So I tried both of those things and for awhile it worked but now it's happening again and what previously worked doesn't anymore if anyone else has any ideas on how to fix this that would be great!
