Mecanim tutorial problem

Hi All,

I have downloaded tutorial project from http://video.unity3d.com/video/7362044/unity-40-mecanim-animation-tutorial

My Unity version is 4.3, it asked to upgrade project.

After importing it gives me the following errors:

SkinnedMeshRenderer requires a mesh with skinning or blendshape information. UnityEditor.AssetPreviewUpdater:CreatePreviewForAsset(Object, Object[], String)

ImportFBX Warnings: Node 'Hips' has invalid Scale ChannelValues (0, 0, 0). Resetting it to (1, 1, 1). Node 'Spine' has invalid Scale ChannelValues (0, 0, 0). Resetting it to (1, 1, 1). ...

Invalid GUIClip stack popping UnityEditor.DockArea:OnGUI()

According to tutorial video at the same page When I click on Robot I should see Import Settings with a mesh but instead I just see a set of textures with no header or buttons whatsoever.

How this can be fixed? I am looking forward to learning unity animation engine. Thanks for your help!
