Cannot get passed Mojang Loading and Skins aren't working

I literally sit there for a long time and the game still won't load. I don't know of a way to fix this yet and would like help on it.

The other thing is that if I do wait like xx amount of hours and the game finally decides to load the rest of the bar, skin's don't work at all when I play. 

Anyone or the staff know of these issues and how to fix it? Please reply to this and help me out.

Thank you.
