Debuger un programme

Bonjour à tous,

voila j'ai essayé une nouvelle macro adapté a mon fichier ci-jointhttps://www.cjoint.com/?CFhrlq5H51W , qui permet d'importer la dernière ligne de ce fichier texte sauf que ça bug " erreur d'exécution '63':

Numéro d'enregistrement incorrect" et je ne sais pas d'ou vient ce problème?
