Windows .exe Modpacks won't start

[xMaschx]

Hi I tried to launch the unleashed modpack today but unfortunately it won't launch.

I pasted the crashlog to pastebin.com : http://pastebin.com/Lw7R3YEu

I also tried reinstalling java 6 and 7 and tried redownloading (deleted everything with ftb and redownloaded it) ftb, the modpack and minecraft but none worked.

Thanks for your help

Uninstall Java 6 and 7, reboot. install Java 7 64bit, reboot, try FTB again and pastebin the console log.
