Wrong backup status for asz backup (Windows 8.1 Pro)

Hi all,
Every day, Acronis makes an incremental backup in a password protected asz.
Backup runs successfully, but True Image Home 2014 says that the backup never run : So, i'm not able to restore a file from Windows (restore menu doesn't appear).

I've delete the job, destroy and create a new asz, create a new job... Problem still occurs.
I see backups in the asz ("find backup" menu), but i'm not able to add them (an error occurs, saying the backup is already linked to a job).

Can you help me ?
Thanks a lot,
Denis.

P.S. : Sorry, i have a french version of ATI, so i'm not sure of the translation :-)
