The problem was that; I had used the already copyed game from previously instalation, winthout a full install after a major windows10 network fault, and restarted it completely. Seems that the DRM do not recognize the game without the full instaltion or osmething else happened that blocked the deactivation. But thank either way, made a new Win install, seems no problem now, and going to install teh game very soon, after redownloading everything again.
