I am having a similar problem as a currently talked about topic. Here is the issue:
RE: An Flidas
[Hello,
I've never had this error pop up before, but when I tried signing into Bungie.net, it sent me an error that said this:
"We were unable to sign you in with your Xbox Live account. Please visit xbox.com and sign in to verify/update your Xbox Live account. This error usually indicates that your Microsoft account has no Xbox Live Gamertag, or that your account must be updated in some way, such as agreeing to an updated terms of use."
When I sign into xbox.com, nothing seems to be amiss. My Microsoft account DOES have an Xbox Live Gamertag, there are no updates that I see, and no terms of use that need agreeing to.
Any help is much appreciated. Thank you.]
as was said here, any help is appreciated. Thank you
