pas de synchronisation dse dossiers vidéo

Bonjour

voilà, je me suis mis, il y a peu de temps et c'est super sympa.

j'avais homeplayer et il marchait très bien, depuis j'ai du reformater mon ordi depuis plus rien à faire, je l'install dans les dossiers rien et pas moyen d'aller dans un dossier

voilà log:
