Hmm? How do I do that? Haha, im really sorry, I don't know much about these stuff. u.u
So the .toa-data folder might be a hidden folder, so you might need to show hidden folders. You could also navigate directly to "YOUR-GAME-FOLDER/.toa-data" in a navigation bar to peek inside of it.
If you can find the profile.json (might appear as just "profile" if you have extensions off) file, you can copy it somewhere else, and delete it, and that should also fix your problem. It probably got corrupted at some point during a save.
