Can't sign into Xbox account on steam

If I click play on the title screen is says Unable to sign into Xbox Live account and when I hit C or click on it nothing happens to let me sign into an account.

Im having the same issue

A lot of steam users can’t even go to the main menu… Paid extra to play the game early rewarded by damn bugs and headaches…

xbox user having issues too

Everyone was having issues today due to server overload.

As per this thread: Gears of war services are currently unavailable (Main thread 5 Sep)

has this been fixed for u yet?

Nah I’m guessing tomorrow there are a lot of server problem and bugs going on…

has anyone resolved this issue?
