Progdvb does not start


Progdvb worked nicely but suddenly stopped working. When trying to relaunch if, i get the splash screen which close after a few second but nothing else happen.
Progdvb is not in the task list.
I tried to uninstall, reinstall, no change, reboot, no change, uninstall and reinstall last version ProgDVB7.27.5x64, reboot, still no success. I found a log file ( )
I did some tests of skins before, not sure it's related.

thnks for any help,
