Windows .exe Launcher stalls at 0% when setting up FML

[Timmervargen]

So I downloaded the launcher to play with my friends. We are using the Ultimate pack on a private server. Launcher starts up fine, but whenever I select a modpack and launch it I get the FML setup popup, but it never moves beyond 0%. I've tried both the Ultimate and MindCrack modpacks, and gotten the same problem with both.

Copy/Paste from Console:

you seem to be having alot of Java errors, Or seem to be.
Try unistalling java and re-install the latest java (or just update)
if that doesn't help, try deleting all FTB things related (desktop and in destination folder of the mod packs) or a 2nd option to deleting, save the FTB modpack folders somewhere else or on a USB then Delete everything, Install the latest Launcher and see if it works again. And if you want your Textures/Saves/etc from your old game, Just move it from Usb or Second copy.
