Tekkit 3.1 modulator field 3.1 Dev build problem

[Tekno]

Title: Tekkit 3.1 dev build error Magor could affect a mod that is in tekkit 3.1

Version: 3.0.3/3.0.4

OS: windows 7 32 bit 2 gig

Java Version: 7 32 bit

Description of Problem:

THIS IS WITH 3.1.0 Dev build!!!! yes i know it says 30.3/30.4 There was no 3.1

<Latest problem> i put down a heat controller for my reactor it is from the mffs mod and it crashes i re-log and load up the world and it crashes both error logs are included refer to error message for what i get it happened with all my errors in the post

<earlier problem> i try to click on the area projector it crashes to white screen so i then reloged and loaded up the world and try to destroy it crashes again so i get single player commands and edit it out with world edit refer to note 1

EDIT I login the reenforced concrete and reactor and mffs items were gone and my texture for stone messed up optimifing?

also i removed my java 6 after this could that be it? ill retry and edit this post for a new log if happens and i waited to post because i was searching other threads and waiting to see if it would happen again i really want mffs in tekkit if its a bug with the mod itself ill send it to the mod maker to see if he can fix it

also tekkit works good on my computer all settings on low and takes up around 1 gig of memory while my system takes up around 350 megabytes and i made the detailed report for the tekkit team if its on their end also sorry for double post computers internet lagged and it posted 2 times please delete last one

<Note1> it might possibly be a id conflict with tekkit it self because first time this happened the glass fiber switched to copper cable but it still had the glass fiber texture when breaking

<Note Note 2> 1st pastbin link is when i placed the reactor heat controler there was no log for when i crashed after reloging and loading up the world

second my earlier problem is the second log the full on of this log is number 3

<note note note> if my computer can handle skyrim it can handle tekkit

Error Messages:

none i get a saveing chunk and white screen not the first time for dev builds
