Armature suddenly start swaying along X axis during animation

Armature suddenly start swaying along X axis during animation

Hello, i animated this model with mocap, for that i adapted the mocap rig to the model and rigged it. Everything was going perfect but after i packed files to post it on Blendswap/OGA i did a last test and now it sways left and right where it should just stay put, also the few animations that put him to the ground now propel him to space and deep into hell.

I added two more motion capture rigs so you can see what they are, one is at the left of the model and has the very attack animation that start swaying(but works fine here), the other in another layer havent been resized and has the death animation.

I would be grateful if someone had a look, i feel it migth be something stupid but i cant figure what.
