I have been playing this game for the past month. Now I keep getting the message "A connection to Xbox could not be established. Please check your internet connection and try again". My connection to the internet is just fine. Please help!
Since upgrading to Windows 8.1 I have the same problem on a regular basis. The time is correctly set, so I don't think that is an issue. Also the card animations stutter hoplessly on my new i3 laptop and my new (4 months) i7!
