How Do I Fix My Motor6D and Animation Problem?

Hi, I set up Motor6D in a wolf model so that I could animate it. I just learned how to do this today, and I thought I did it right. But when I went to animate it using the animation plugin made by ROBLOX, it all started bugging out when I tried to rotate it but not when I use the move tool on it. Every limb but one leg that is. Is there possibly something I did wrong or is there a way to fix this, or am I being a complete noob?
