Removing the advanced machines mod altogether seemed to do the trick. Is there a way around this, though? I want to use the solar arrays in the mod to conserve space...

I do have advanced machines. I assumed that because they're in Tekkit by default, I could use them safely. Where are the sound files for the advanced machines mod?

Launcher/pack Version: Tekkit v 2.1.1 Operating System: Windows 7 64 bit Version of Java: v7 64 bit Description of Problem: Every time I reach certain boundaries in the world (not very far from my spawn point), the game freezes for about 5 seconds. A white screen then appears, and after approximately 20 seconds, the window closes. The blocks outside the boundaries are there, and mobs can come and go between the boundaries without anything out of the ordinary happening. Additionally, after the crash, if I load my game up, and I saved the game close to the boundary, I can pass through without a crash. The world is functional afterwards, and I can cross the boundary from this side to the original. However, if I attempt to cross back over to the other side, the game crashes, again.
