All mangas/catalogues gone: "Error! Can't add this site config"

[Juicebox]

Hiya,

opened app. today only to find everything gone. When I try to add a catalogue, I get the error:
"Error! Can't add this site config" (create folder Parsers in folder /MangaWatcherX/”

I don’t mind adding my own folders, but I’m not sure what name to give them …

Version: 3.1.3.4

NOTE: The folder “Parsers” is already in the folder “MangaWatcherX”, including a bunch of sub-folders inside it with the name of a bunch of catalogues.
