Title: severe error. not to sure what mod

Version: 3.0.3/3.0.4

OS: windows 7 home

Java Version: 1.7

Description of Problem:

the starts loading, boots up, and then while adding the materials it gives me a severe error. i haven't changed anything since the last time i ran it, but now it doesn't work. It was almost positively caused by my computer crashing whilst the server was running.
