I updated my Surface to Win 8.1 update 1 - and then there was an update to AlphaJax.
Now on my WP8, Alphajax is the way it was before the Surface update - normal.
However, on the Surface - AlphaJax is acting like I am on a new profile. I have new games starting up, all my previous history is lost, the ongoing games on the WP8 are not available on the Surface, and all new games started on the surface are not available in the WP8.
Also, I have internet connection (via WiFi) on the Surface - however, every time I start AlphaJax - flashes "Retrieving User Info".. then my Xbox live handle and pic show up on the top right, and then a white box with an error message "Error You need an internet connection in order to play. Please make sure you connection is working or try again later.". Like I said, there is a connection, and I can play others.
Lastly, on the surface - my achievements are still there (correctly). I have also uninstalled/reinstalled - with no luck.
