I am totally stomped on this one. I have looked into other questions of people having a similar problem.
I have "manipulate center points" turned off
It is deformed with Automatic weights. (See last image)
I made sure all of the vertex groups were deleted before putting on the armature
Made sure all of the modifiers on the model were applied
Made sure that the Armature was on the top of the Modifier stack
Made sure that my mesh has nothing locked in the Rotation/Location/Scale
Applied the Rotation/Location/Scale of the model
I have also tried to use Envelope weights instead of automatic and it gives me a weird result. See the first image. It deforms to the mesh but part of the mesh does not move
If any further information is needed to answer this question please let me know and I will update.
Please help Thanks
