Xbox 360 Sign in issue on Xbox One

Using the Backwards Compat feature is great, and it used to work perfectly fine for me, but all of a sudden anytime i try and sign in (which it always asks me to do) it tells me it cant, why is this?

I recently purchased an Xbox 360 title digitally, so i could play it on my Xbox One.

Now that its downloaded, it loads up fine, however when it asks me to sign in to Xbox Live (again) via the Xbox 360 emulation, it keeps giving me the error message

"Sorry this profile cant sign in to xbox live on this console, to fix it please download and try again"

firstly, what does that even mean? secondly, why cant it sign in all of a sudden? it worked fine with other 360 titles i played.

The only thing ive done differently since the last time i played a 360 title on my xbox one, was change my Xbox sign in name, and its the only thing i can think of that might cause a problem, as the Xbox 360 sign in STILL displayed my old gamertag rather
than the new updated one.

Game just cost me £15 so id like to get this fixed ASAP cheers.

360 and One on same gold account

If I sign in to Xbox Live on my Xbox One, will I also be able to sign in on the same account on my 360 at the same time? Say someone is using the Xbox One in the living room and I'm playing my 360 in my bedroom. Will I be able to use the same account?


WHITTEN: Yes this works! You'll be able to be signed on with the same gamertag on both an Xbox 360 and an Xbox One console at the same time. However, like today, you can only be signed into one Xbox 360 and one Xbox One at a time

Backwards compatibility question

You can login, make sure you are logged into a profile on your xbox one, then hit the back and start (view and menu) buttons in x360 mode... That brings up the option to sign into profiles and download profiles.

Even if you use another xbox 360 it should let you login to a xbox 360 profile and it should just say it was last signed in on another system. I'd make sure you are signed into a profile, if you are trying splitscreen stuff make sure your friend signs into his xbox one profile before then signing into his xbox 360 profile.

Awkward, but it works. Been busting up borderlands splitscreen in bc for a couple days.
