Hi. I have download the miracle box and the vcom drivers and i have download the tutorial on YouTube but when I try to install the drivers it does not succeed. The message say the material does not be installed, an error occurred in the installation... The INF have not information of number signature... (something like that. I have take a picture but I don't know how to put it here.) In French the message say:"Le materiel suivant n'a pas été installé:Média Tek DA USB VCOM Port
une erreur s'est produite lors de l'installation du périphérique.
Le fichier INF de tierce partie ne contient pas d'informations de signature numérique." So i Am at the step where i may install the Média Tek USB VCOM drivers.
