When I open the Minecraft PE app my skin usually pops up on the side of the screen next to the main tabs but recently my skin hasn't been popping up. It will be completely invisible not even the empty model pops up so I tried shutting down my iPad..... nothing, I tried restarting the app....... nothing, I tired deleting the app............nothing at this point I don't know what to do all I want is to play with a cool skin. 

Just a BTW i did get my skin from the internet but it always works.
