Hello guys ! I have a problem since last week and I see that the developers are not helping me at all. I have a problem , I can t login in my xbox acc to play halo reach, everytime i start the game i recive an error that says Singin error and something about xbox live, at this moment i can t do anything , but to click retry forever or cancel and all i can see is halo reach background. the idea is that halo worked before, but since i met this problem i didn t find any fix. When i asked in customer section for help , they told me that they don t know what is this bug and how to fix it . 
So i hope you are more deticated for helping than them . THANK YOU !
I did, but overall The bug is fixed
