Watch dog do not start

Hi, Im using a Windows 10 machine with Xibo player 1.7.7. Xibo was functioning smoothly until last week when the player suddenly crashes and the WatchDog app was not running.
I tried to open WatchDog app, it opens, but when the player crashes WatchDog do nothing.
I tried to repair, uninstalled it, but WatchDog stills not functioning.

Any advice?
