Oh then I know exactly your problem is. The material and texture in blender would look fine and dandy on the GUI but will look pink and white IF the texture hierarchy is broken and transferred.
This would make sense since you got a .blendfile rather than a .fbx

You need to reload all image in the texture you have here>>302372394
Click the Folder icon on the SOURCE and place again the image that was supposed to be there.
