Where does the new .txt file go? I put it in Localisation folder.
What text file are you referring to? Jukebox View is a view, not a text file. Depending on what view you're currently using, click the upper left corner of the main panel (Albums, Albums & Tracks, Artist, etc) and the drop-down will have an option for Jukebox.
Again I don't know what text file you put in the Localisation folder, but get it out of there.
