Own made animations and mechanim problem

I have made a couple of animations in the Animation view in unity, that is i have a made a couple of animation clips that i want to use in mecanim. I alot of the free animations up and running and that isn't giving me any problems at all but when i try to use my own animation clips they wont work. The error i am getting is:

Animation clip 'testanim is not retargetable. Animation clips used within the Animator Controller need to have Muscle Definition set up in the Asset Importer Inspector
UnityEditor.DockArea:OnGUI()

I have looked all over google for a solution to this for a couple of hours now and i am not finding anything useful. I hope someone might be able to help me!

 

up. I have the same problem!

 

I have the same problem too. When I go to the animations tab It doesn't even list any animations. But I have a bunch of clips in a directory. When I try to use them it gives me that error.
