Oi, the proper solution is reinstalling the FCam driver using apps. (meaning, uninstall all FCam using apps, then reinstall all FCam using apps.) Then reboot. No need to downgrade (depending on how much risk you want to take that something somewhere doesn't update right, I'm pretty sure you can skip the reboot. Alternatively on the really safe side, you can stick another reboot between the uninstall and reinstall),
