If you got a message about putting pictures in a folder, that would be after clicking the "local" button.
You probably want to select "E621 favorites", put your username and click the "load favorites" button. This does not require putting images in a folder.
Don't forget to select a gamemode, else the game won't start.
It is very difficult to help you unless you explain what you have done/tried as precisely as possible.
Once the "load favorites" button has been clicked, the number of loaded pictures should update to something above 0. Pictures will be displayed once the game is started.
If they don't seem to be the correct pictures, make sure you entered the correct username: entering a username that doesn't exist gives the default latest posts.
Checking if a username exists isn't directly possible afaik, but I might try a workaround.
Thank you for describing your steps! In this case, it really looks like the username you entered doesn't exist.
It will be the same if you go to e6 and type "favoritedby:username" in the searchbar. If this does not give you your favorites, neither will the program.
For example, "lopunny" is a username that exists and has favorites. Going to e6 and entering "favoritedby:lopunny" will give you the expected results, and same in the program if you type the username "lopunny" in e621 favorites.
I am working on a way to somehow tell if a username exists, I would suggest waiting for the new version that will hopefully be published in a few hours from now!
I have no idea why your username doesn't work.
Please check you are able to get the expected results by going on the e621 website and typing "favoritedby:yourusername".
The other usernames test show that the feature seems to work for other users, and it is weird that it wouldn't work with yours.
Just a guess, but if you changed your username, maybe you need to enter the username you first used when signing up. It is up to their implementation at this point.
