My Skin Is Not Showing Up And I Cannot Find Any Videos On It that work.

What I expected to happen was...:
Load Into My Minecraft World And My Skins Would Show Like Normal(Affects All Versions)

What actually happened was...:
Load Into Minecraft World, Steve or alex, search youtube and google for 5 hours straight, nothing.

Steps to Reproduce:
1. Open Minecraft Launcher
2. Put On Custom Skin
3. Load Into Singleplayer world.
