So, I went to log on to my xbox live profile on the xbox. It asked me for my Microsoft username and password, which I filled in. I tried to sign in, but it showed me the error code 80154016. I then went on to my Microsoft account on my computer and signed in. Once I did that, it showed my xbox live gamertag as some random profile, the one that I am typing this with. Is there any way to get my profile (with a gold membership) back onto this Microsoft account, otherwise it is impossible to sign in to that account, because apparently no emails work with it.
