Hi Ali! I'm Rostom, an Independent Advisor. I will be glad to help you here.

Make sure to sign in first her account to your console.

Press the Xbox button to open the guide. Select your gamerpic in the upper-left corner of the screen, move all the way down and select Add new.

Enter the email address for the Microsoft account that you want to add, and then select Enter.

I see. Let's clear your local storage for Xbox 360.

Go to Profile & system > Settings > System > Storage. On the Manage storage devices > Clear local Xbox 360 storage.

Perform then a power cycle of your console. Press and hold Xbox's power button for 10 sec. Unplug the power supply for 30 sec. Plug it back in and turn it on again.

Once booted, try playing the game again.

Got it. Please try to simultaneously press the 2 smallest buttons (BACK and START) on the front of the controller to bring up the original Xbox 360 menu. From there you can add/sign in second player's profile and play together.

Hi Rostom tnx

I added her account on my xbox one but i cant add hers to the game

The guide in the game that looks like xbox 360 just brings my account, even i start the game from xbox one home page just with her account.
