Error Log:

[Wally]

if i did happen to post this in the wrong section, can someone tell me what the right section is? ^_^

[Wendo]

So, you have

A problem has occured during mod loading. Likely a corrupt jar is located in your mods directory

which seems pretty obvious

and

Unsupported major.minor version 51

a search of that would lead you here, in short, upgrade to java 1.7

I can't make my own thread yet so I'm just going to post here. At least you get a bump.
