so, way back like maybe 1-2 years ago when i first made my xbox acct. i made it with my old yahoo email, well i have no way of accessing this email anymore so i can't change it. its not a HUGE deal for the most part, i just have problems signing in on xbox.com or similar sites. this is actually the first time ive been able to sign in on here. i have no idea how to fix this, or if there is a way at all. any suggestions?
