Dear Markus,
It finally works!!! Thank you so much, I am very much relieved.
Dear Stefan and Markus,
Thank you very much for your precious help and advice. I will avoid switching language especially between desktop and laptop, but I think all my backups have always been made in English version, I sometime switch to French when I have a doubt on something but usually, I privileged the English version.
Very big thanks to the fantastic WDP Power user and Support team and Senior member.
I wish you a nice beginning of the week, with my best regards.
Olivier
