Yogbox keeps saying can't find jar...

[Hecgunner]

I downloaded the Yogbox and installed the modloader yet it still says "can't find jar" whenever I try and open it...

You do not need to install modloader because it IS already installed, just not in the minecraft.jar. So just get a new fresh install and then it should already be fine without even having to install something yourself.
