Why can i only play minecraft demos?

Ok so i've owned minecraft for a while now and just recently deleted it off my xbox to open up some space, i've redownloaded it so my little brothers can play offline and now i can only play the demo version on profiles without xbox live. It used to allow me to play the full game before and now it only plays the demo!

Because you didn't license your profile to said xbox, so without your profile on their (connected to live) you won't be able to. Before the terms and agreement changed you would've been able to, now you need to be connected to the interenet and transfer the license over to said console

I do believe they would have to sign in with your account(the one that downloaded minecraft to begin with)
