If Windows Journal starts crashing every time you try to open it, these instructions might just fix it (thanks to David Bradley):

  • Close all open instances of Windows Journal.
  • Open up windows explorer
  • Type %localappdata% in the address bar
  • Go to MicrosoftJournalRecover
  • Move all .bak files to a temp folder on your desktop
  • Restart Journal
  • Delete temp folder
