Multiplayer & Xbox live Family Settings

Hi there,

ive had the master chief collection for a while now and have always been able to get around this glitch by following the advice in forums on here. However I can’t access multiplayer it says my Xbox live settings are blocking multiplayer. I’ve opened up all my privacy stuff, have an active Xbox live subscription currently a waste, I’ve cleared system data, done hard resets, done off at the wall, cleared persistent disc storage and now it is driving me up the wall!

any ideas/suggestions?!

thanks
