Iv'e been trying fix this all day; I don't get on Live vey much because I don't have it so every time I want an update or dlc I take it over to my cousins house. Well today I had to do that thing where you have to put in the E-mail and password. After trying forever to remember it since I haven't used it sense the xbox came out I put it in and it says this, "Sorry, either that's the wrong password, or the email you entered doesn't have an xbox live membership. Code 80048821"
I've tried changing the password, clearing the cache, looking at other answers, signing into the Microsoft account instead of xbox.com, updating my info and nothing works. After I tell the xbox to remember my password it goes: Bloop, you have signed into xbox live, then the error pops up giving me the message. Why can't I get in, I've tried the moderators awnsers before and that doesn't work.
PS. I can trick the system into updating the games by staying signed out and then signing in when the game tells me to online. It updates but then I can't get back online.
