I saved and locked presets before "logging in" and can't unlock them

Hey Frank, been using kustom for nearly 2 years and thankfully haven't needed to make an account here until now. I wasn't aware of the log in feature and was in the middle of creating a series of wallpapers based on the first one i put together. I'm able to send both files and prove the emails from them are mine. Are you able to help at all?
