Problems Launching Monster?

[KaptainKomedy]

So when I try to launch monster I press launch and then all of the buttons grey out but I can still scroll, look at other modpacks ect.

I get this error log: http://pastebin.com/uTiHkz7Q

EDIT: It's not just monster actually, I'm fairly certain it's everything.

It looks like when you updated Java, you installed the 32-bit version of 1.7.0_51. Go ahead and uninstall that and try installing the 64-bit version found here:

If the issue still persists after this, would you please post a fresh console log to pastebin.com?

I solved it but thanks mate, in the end I deleted the FTB folder in appdata (which I previously couldn't find) and reinstalled the modpack.
