FBX file not animating properly in Unity

I have an FBX file I created in 3ds Max of a simple coin rotating. Whenever I import the FBX file into Unity and put it into the scene, the mesh doesn’t rotate at first. Then, when I change the animation to “Legacy”, the object disappears entirely. When I uncheck “Play Automatically” in the “Animation” component, the object is there, but it still doesn’t animate.

Anyone have any similar issues?

Now I have not had that specific problem because I use blender not 3ds Max but I have had animation problems. These are the settings I use, maybe they’ll work for you.

Under Rig I use:
-Legacy
-Store in root(new)

Under Animations I use:
-Import Animations (checked)
-Wrap Mode: Loop

Rest are pretty self explanatory, I usually use them alone.

On the Prefab that I actually use that FXB on I have the animation set under “Animations” and under the “Animations” array. (with the size of 1 and the same animation in the root; this is all default I don’t touch it)
I also check the “Play Automatically” and put "Always Animate under Culling Type

Hope some of this helps.
