So I am pretty new to blender, this may be a dumb suggestion, but in the window with the model it sort of looks like you only have the model selected, no textures. In the top right corner of the model window you should see 4 buttons that have symbols that sort of look like bubbles. The one on the left I believe is for wireframe, the next one to the right (which is currently highlighted) I think is model only, the next one should show textures, and the final one should show the world details. Try clicking on of the right two bubbles to show the skin.
Again, I am new to this and going off of memory, so I could be way off, but give it a try
