2 days ago, CCSaga (played on my laptop, Windows 10), prompted me to login via Facebook (which I hadn't previously done, quite deliberately). In order to progress, I logged in via FB and as soon as I hit play, the entire app crashed and disappeared. I reset, repaired, reinstalled, troubleshot Windows Store Apps, did a clean reboot and then a clean reinstall of Windows 10 . . . all things suggested through this website. Unfortunately nothing is working. (Although CCSoda and CCJelly are still working with no problems.) Any suggestions? Many thanks! I would prefer to play as I was before, without connecting to Facebook.
