Animator "not initialized when importing FBX from "Mixamo" or "Blender.

Hi, I guess this is kind of a newbie question, so sorry about that.

I am trying to import an FBX file that I downloaded from “mixamo.com” into unity. On the inspector I can see on the “Model” on the animator “Not Initialized”. On the animations tab there is only one animation that is actually all animations together, but even that animation I can’t run. The same problem happens when I try exporting from “Blender” to an FBX and tried to import it into unity.
I looked everywhere but I can’t find the problem. What should I do?

Thanks!

Your best bet would be to follow a few tutorials, here is one I prepared earlier which uses Mixamo assets too:
