Mac FTB: Unleash Download Crash

[Wintermelon]

Hey,
So I'm really keen in playing FTB: Unleashed but every time I try downloading it, My launcher will crash unexpectedly. My Java and Launcher (1.3.3) is up to date.

OS: Mac

Here is my log on pastebin.com: http://pastebin.com/ZCRBc9sk

Any solutions will be greatly appreciated!
