As a Windows player you should do regular backups of the 3 files player.prf, player_backup.prf and player_backup2.prf in the folder C:\Users\Username\AppData\Local\Packages\828B5831.TheSecretSociety-HiddenMystery_ytsefhwckbdv6\LocalState and, if you have non-wiki friends and love them, Friends_List.xml in the subfolder "Social" (will help Neo to locate them). AppData is a hidden folder .. Neo has a link to unhiding procedure in the first thread below.

Generally if the game doesn't open anymore you can first try to copy the prf-files from your backup into the LocalState folder and Neo always suggests to delete everything from the Social subfolder -> that will be restored from the server. If it doesn't work then uninstalling and reinstalling the game may help. After re-install the player.prf is copied to LocalState (which is emtpy at that time) and then the game is started first without internet connection to see it if works again. Then you can start with internet connection so that all the files for the Social folder are restored from the server.
