OneNote cannot read the notebook cache file because it is from a pre-release version. OneNote will delete and rebuild the cache. This will delete any unsynced changes in your notebooks. If you have important changes that have not been synced, click Cancel, start your earlier pre-release version of OneNote (reinstall if necessary) and fully sync OneNote before upgrading.
