Hi, I originally tried to change my Minecraft custom skin and after I selected it, it gave me the Alex and Steve body types, but absolutely no character was shown on screen. After selecting the option- I now cannot see my character at all and if I try changing the skin to another custom skin, my character will still remain invisible no matter what. I also cannot go onto any worlds without the Corrupted Skin message popping up. 
This problem does not seem to be occurring with any of my bought packs- only my custom skins. 
If you could please help me resolve this issue, that would be most appreciated. I know that you guys are busy, but thank  you and I hope you all have a wonderful day.
