Problem to open VM Windows 8 after update OS X Yosemite to El Capitan !

Hi !

I am a french user.

I used Vmware Fusion on a iMac under OSX Yosemite without any problem.

After I have installed OSX El Capitan v. 10.11.1., when I try to open my virtual machine (Windows 8) I read this message :

"Impossible d'ouvrir le disque '/Users/Gilles/Library/Application Support/VMware Fusion/Virtual Machines/Boot Camp/Boot Camp.vmwarevm/Boot Camp.vmdk' ou l'un des disques de snapshot dont il dépend.

Échec de l'activation du module 'Disk'.

Échec du démarrage de la machine virtuelle."

I have updated Fusion to  version 8.02 but the problem is the same.

Thank you for your answer and your help.
