I keep on trying to start up Attack of the B-Team, and everything is working fine until Minecraft itself starts up. Then it says at the top of the window, 'Minecraft 1.6.4 (Not Responding). What the heck is going on? It worked before, now it's simply refusing to work. Can someone help me?

I'm trying to get The Diamond Dimensions modpack, but whenever I paste the URL the DD modpack tab shows up, and when I click on it to play, it says this: http://prntscr.com/4es4jt
