Basically the fix for a windows store issue is to uninstall the game within your current account, create a new local account, download the game into that new account, run it till you get to the menu, exit that new account and go to your old account, re-install
the game and it should pick up your cloud data.
From the above thread this almost sounds like a common fix for MS account issues.
Since this is happening in multiple games from multiple vendors my WAG is that the last MS update made a change that wasn't passed down to the app developers. So when a new version of the game came along it was no longer compatible with how MS is doing its
accounts within the store. All it would take is MS adding an extra byte into the DB record that stores the account information.
Note: GL updated their game on the 7th
QUESTION: To confirm my WAG, was any of the other games that have an issue recently updated (between MS last update and the date it stopped working)?
Did the other games also fail on the 7th or did they fail at a different date?
But, the last 2 updates from GL shows that there is very poor communication between MS and its app vendors and that GL's needs to do better QA testing. They should be working side-by-side to ensure 100% compatibility. There is no excuse for either company
for not doing this. We are their customers, We pay their bills. How much time did each of us spend trying to correct their issue? If MS and GL was honest they would have immediately responded to this thread and gave us a detailed solution. Instead both
GL and MS played the blame game instead of accepting responsibility for their actions. People make mistakes, emails are lost, that is forgivable, but not accepting responsibility for the issue is not.
