Hello gionata73,

updating with the 3.5 demo I often crashed the pc,
I am not quite sure what you are trying to tell us here.
It is not possible to update a full version of the software with the trial edition.
I'm afraid that we have been unable to find your registered user details from your forum details.
Could you please contact support with your registered licence details?
And we will look into your problems with 3.5
Mark.
