Thanks again for the video!
The folder to rename is the whole deepdwn folder in %appdata%, so you’d be renaming C:\Users\YourName\AppData\Roaming\Deepdwn to C:\Users\YourName\AppData\Roaming\DeepdwnBackup (or similar).
I’m not confident that would fix it, but it’s worth a shot in case something is corrupted. I’m working on adding some logging that ought to help if the issue is some kind of error while reading your files.
