problem with animations from mixamo please help

HI. I downloaded some animations from mixamo for use with my 3d character. When I go to apply them in mecanim the animation doesn’t play and my character ends up halfway in and out of the ground.

Can anyone please help me figure out what I am doing wrong?

Could be a number of issues. Humanoid rig? Avatar definition of the animation set to inherit from other avatar = character avatar?

Ground issue has been asked/answered in the forum a lot so you can check there for an answer.
