FML flatly refusing to load.

[Xovvo]

Operating System and bit type: Windows 8.1 64-bit
Java version/update and bit type: 7u45 64-bit
Launcher version: v1.3.3
Console log, pastebin.com link: http://pastebin.com/Xt1PZJRX
Description of the Issue:

So, trying to load TechWorld 2 modpack (or other 1.6.4 modpacks), the Launcher crashes before even properly loading the game.

So that's cool.

My Techworld 2 server is running just fine, however.

So, what just happened and how do I fix it, if I may ask?
Thank you kindly for your time.

First try force updating the modpack using the button in the options tab. If that doesn't work, follow this guide: http://desk.feed-the-beast.com/inde...ticle/View/54/0/basic-troubleshooting-updated
