Tekkit crashing

[Myhat2you]

Hello, recently one of my Tekkit worlds has been crashing the game. I am able to go onto other worlds and I set my graphics to the bare minimum to play the game. I have a pc with 8gb of ram, runs on windows 7, and is 64bit. I'm pretty sure I have the latest version of Java and am running tekkit on the latest version. I haven't attempted to change any of the coding or add any mods, everything was running fine till recently.

The problem is, after I set the game up and click single player then play on my world the game closes to my desktop. Please help.

 

These are the last 6 lines of code on the console after the crash:
