Hey there.. I'm french, so I'm sorry for my bad english, but I think I can explain you what my problem is.
So, one hour ago I tried to connect to Xbox Live, but there was an error message with the code 80151012.
I did my little search on Internet, and I tried all the solutions, like delete my profile, and also the password recovery. And it still don't work.
Now, my profile is not even in my Xbox, and the same code still appear when I try to re-download my Gamertag.
What can I do for it ? I've tried all the methods, so I don't now, maybe you can help me please ?
