Thank you for your help JohnjohnJohn.

I have these 3 informations (serial number, digital ID and Authorization number) but the soft does not ask me anything, and there is nothing in the manual about that.
The soft just say Ok your are authorized but when I use it the authorization is gone (the strange problem is here - which is not realy exciting)
I'll see that tomorrow. If I find the good way, I'll say it. Am I alone with this problem ?

Thanks again,
Bertrand
