Falls irgendwer bei Xbox 360 das Problem hat das sein Profil abgemeldet wird sobald er ein Spiel/App startet oder zum Xbox Dashboard zurück geht, hier ist die Lösung!
1. Go to
http://account.live.com/
2. after logging in scroll down a little and then click "edit Security Informations".
3. enter the Code that they send to the email or cell phone that you entered as a contact medium
4. check if you entered a phone number, if yes and there is still the word "confirm" below, do that!
5. check if you entered an alternative email, check if you have to confirm that as well. If there is no "confirm" word below, then its already confirmed.
6. DONT DO ANYTHING ELSE on that page and close it.
go to your Xbox now.
1. Logout your profile if it isnt already
2. Go to your Harddrive, select your Profile and delete it: ONLY PROFILE!
3. Go back to the screen where you can choose cloud or Harddrive. Click Y on Harddrive
4. Choose to delete System Cache
5. When its done, open the Guide with your Guide Button and select "Download Profile".
6. Enter your Email and Password and download your Gamertag.
7. When its done it displays the Gamercard and the option to save the password, check this.
8. Hit ok, now you will miss your Dashboardbackground, that can be chosen again from your Backgrounds.
9. Check to start a game and go back to Dashboard, worked for me.
