That sounds as if the Witcher version and the mod version do not match. Please double check that you really have the latest Witcher update installed.
Also make sure that you didn’t accidentally disable automatic profile updates in the config app.
If that still doesn’t help, uninstall the game, delete its folder and reinstall to be 100% there really is no other mod installed that might get in the way.
Last but not least (just mentioning it, not suggesting anything) make sure that you don’t accidentally use a non-legit version of the game. Should that have been the case, please make sure to never ask for support here again.
