Error trying to load Magic World 2 modpack from FTB launcher

[Axolotl9250]

Hi, I just got an update and restarted the launcher, If I try to load MAgic World 2 I get some error and the launch cancels, but if I try something like HatP
ack then stuff works fine. The log is at this pastebin: http://pastebin.com/JW3vLdnr

For some reason ForgeModLoader can't configure the minecraft home at C:\Users\Ben\Desktop\FTB\Magic_World_2\minecraft and there are errors about major minor version numbers 51.0.

I'm guessing the update did this - but I am only guessing.

This is for MW 1.1.2, I'll try see if 1.1.1 still works for me.

[EDIT] Nope, 1.1.1 says the same thing :/ Hmm... weird.

Best,
Ben.

I'm not a hero on these logs, but I do see multiple versions of Java.
Stick to the newest one and preferable 64 bit.
(java tends not to remove the previous installations when updating)
