I tried to do exactly as you wrote, deleting the driver (fig. 1), then I tried to install Total TV.
During the installation appears the same notice of the previous post, decided to continue the installation.
Installed the new driver without wizard (fig. 2) and tried to open unsuccessfully TerraTec Home Cinema.
I tried to restore Total TV, but the same notice appears.
I tried to restart the S.O. in every step with the same conclusion.
In the past, I had installed it with a new S.O. installation. I hope don't have to reinstall the S.O. again to have it.
