How Can I change the 3rd person controller Mesh?

The default 3rd person controller of unity has got a Constuction worker, I must change the mesh and put my own character. I did this:
[17498-screenshot±+06_11_2013+,+13.jpg|17498]

and if I select my own mesh it says: SkinnedMeshRender requires a mesh with skinning or blendshape information. UnityEditor.DockArea:OnGUI()

HELP!!

Delete Skinned Mesh Renderer, and put Mesh Renderer instead… That’s all. You can put usual things in this mesh renderer. This error happens because the mesh you trying to use is not skinned (can be fixed in model proporties).

hey thanks
