mixamo to blender multiple animations

When I bring in a character with an animation and import it into blender everything works great animation plays perfect BUT I download the*strong text* exact same character with exact same format same model and same armature but when I bring import another skeleton I should just be able to use the animation that is on that because its the exact same armature yet when I bring it in and try to use the new animation with the action editor I get a very weird deform on the original armature... Any ideas?
