Mybooklive - Can't access PUblic Shares

Hi

I cannot access my Public Share on my Book Live.
It says in french “Unable to open file” Shared Videos “because you do not have permission to view its contents”.

I am on mac os X ( i have tried on snow leopard, Lion and Mountain Lion).
I can access to every private share.
I also can access to Public share when connecting via wd2go.com.
I have tried to reboot and a quick restore.
The Mybook has been updated in august 2012 ( the problem started before that update).

Can you please tell me how to solve this. I cannot have access to many files and it is much too long to copy them from wd2go ( i have 1to of files in public).

Regards

Thanks

try mapping the share
