Hello, I was letting my friend use my account to download zombies before he bought it so we could play as soon as it downloaded, but he changed my gamertag I need it reverted

Youd have to pay to change it back. Theres no way around that. You are responsible for your account at all times.

Also sharing your account is actually against the rules and could result in both you and your friend being banned so id advise against doing that going forward.

i bought it from a friend and he transfared his account to my email and gaved me the account so i thing the ID is in his email cause he bought it

and i bought it from my friend cause we dont have paypal or credit card in our country

I’m having trouble with Game sharing. Me and one of my other friends have done it before but this was a while ago. Me and my friend followed a video on how to Game share. After he had downloaded games he wanted off of my account, He tried to play one
of the games he downloaded but it said,”the person that bought the game needs to sign in”. My games will not load, they will be stuck in the loading screen, and even if they do load the lag so bad.

Ok so if that's the case why did it happen to my mate who bought the day one edition and nobody else has touched it? We have also established that it was a new gold member he was playing with the night before he was playing with and whatever they installed
on their xbox got transferred to his Xbox for download too. So how do I set this up as a ring with my friends so we all buy a game and share it amongst us all?

My friends & I did it during the Halo 2 days. I still remember when my best friend joined us for a LAN game on his wedding day. He never played before so we were calling him a noob & so on... Then he grabbed the Scorpion tank & laid waste to everyone. He
had so much fun, we made him late for his own wedding - his wife never lets us forget that.
