I bought roughly one month ago a Nokia Lumia 720 which uses the WP8 and I've been facing a problem with the Xbox services like Games and Music.
When I try to connect I get the error coded 80154017, saying that there was simply a flaw to fulfill the request.
I am also having troubles when trying to connect to the account in the PC, when I log in I'm greeted by a screen to update my Xbox account to a Xbox Live account, but when I try to continue it leads me to a screen saying that I "found a glitch in the system".
And, if that was not enough, I can't connect to the W8 Games app because I get the error 0xc101a247 and a message saying that I don't have a Xbox associated to the Live account and it tells me to create a Xbox profile to use with the account.
I've had no success trying to search for the error codes, nor any solution I found online showed itself useful...
Just a reminder: I don't have a Xbox console, the only devices that I have which can use the Xbox Live are my PC with W8 and my mobile with WP8.
