Pb téléchargement via beezik

Bonjour,
Actuellement inscris sur le site de téléchargement gratuit beezik, j'ai des problèmes concernant l'enregistrement des titres audio.
Ce pb m'est survenu il y a quelques jours, je ne l'avais pas auparavant. Je rappelle le système, on veut téléchargé de la musique, on regarde une pub et on a 6 secondes pour télécharger le titre. Le pb survient à la fin de la pub, lorsque l'on veut enregistrer le titre, j'ai eu ce message:

An Error has occurred in this application. java.lang.NullPointerException at com.beezik.web.controller.member.music.MemberMusicUpdatorController.getUrlLicenceDRM(MemberMusicUpdatorController.java:259)
