Some of the tools options are saved in other folders. Only Uninstall/Reinstall of the Photoshop will not help. With uninstalling you need to delete the main Photoshop folder and any other folders with "left-overs" that Photoshop created. So, not just Uninstall, delete this left-over folders with probably tools config stuff, surch in you account folder in windows for Photoshop folders too. This must help...
