jamiedizzle2

Hey, I've recently created a custom mudpack called Jamiedizzle2's Amazing Modpack I've followed many tutorials on how to make them but when I click play, the technic launcher disappears then reappears a moment later. I've tried reinstalling java and the technic launcher but neither has worked. Here is my log: http://pastebin.com/DSKAhJED Here is the pack: http://www.technicpack.net/modpack/details/jamiedizzle2's-amazing-modpack.551837 I really hope someone can help me
