Halo Spartan Strike on Windows 8

Hi,

I'm having an issue with 'Halo Spartan Strike' On my computer. Whenever I try to play the game I lose the progress after playing it. It suggests I sign into my Xbox account so then I don't lose my progress. I do that but then it comes up with an error message
saying "Sorry we can't sign you in. Try signing in at Xbox.com, then start this app again." and it doesn't work.

:)

 

Halo Spartan **** can not start.It keeps asking me to sign in with Microsoft account.

I have windows 10 and it does the same to me, also the same for halo spartan strike, this is on since 2013, come on please help.

 

0xC03F300D error code logging in to Microsoft Mahjong

I am having this same login problem for all of my Xbox apps on Windows 10, including Halo Spartan Assault and Spartan Strike as well as Hitman GO. I have tried everything that has been suggested. This issue is quite annoying.

 

I'm also having this issue, but on Windows 10. It logged me in fine the first time I started up the game, but now it wont sign in even after restarting the PC, reinstalling the game, and also reinstalling the xbox live app. Any solutions yet?

 

Bump. Okay, if no one has a solution, does anyone know where to find it? Who do we call?

 

Having the exact same issue, anyone have any luck?
