Today , the new windows 10 update appeared and lasted 1 hour during the install.
The update was successfull but after it, no more task for LHC project provided by the server.
So I took advantage to update virtualbox and its pack extension too, and I removed and joined the project a new times in order to fetch new tasks.
And now it is running fine.
Hope it helps people in the same situation...
