[Minecraft has crashed! Failed to start game]

Does NO ONE have anything for this? I've been having issues for so long that I've literally gone back to vanilla because I just wanted to play for at least a little bit... someone please   

[Minecraft has crashed! Failed to start game]

Hey, I've been having a pretty big problem with Voltz... It won't start, although FML does in fact run and setup the minecraft environment... However, as soon as FML closes, the Voltz-modpacked Minecraft window goes black and waits a few seconds before displaying the classic Minecraft error. Anyone able to help?
