Marketplace won't open

I am not able to open marketplace(when i try to open it nothing happens) also I can't change my avatar. Multiplayer still works. When I try to open marketplace in game it says invalid session try restarting. I have restarted the game and the Xbox, signed out signed back in, uninstalled reinstalled. Nothing seems to be fixing it. Oh and when I try to use zig zag texture it downloads but won't import, other texture packs work though
