Upgraded from trial version. Lost latest version of book

Hi all.
My wife has been using the trial version to work on her book. We purchased and added the key and now the latest version of her book has gone. The nearest we can get is something from 3 weeks ago. Any ideas?

Nothing disappears of itself and Scrivener does not keep an internal copy of projects within the program files, so the project is still there. The only reasonable explanation is that you looked in the wrong place.

Search your computer and any removable drives you use for .scriv folders. If that doesn’t help, search for text that you would expect to find in the project.

Simply registering wouldn’t change anything about your Scrivener installation or data. You can also look in the Tools -> Backups tab to find Scrivener’s automatic backups.
