I think you mean stuck in unlicensed, totally uninstall the SU app, (
no need to uninstall the driver), then in the start menu right click 7-zip, or Win-Rar, and open as admin.
Navigate to: C:\Program Files\WindowsApps\, and delete the DTS Sound Unbound folders (hold shift), open the store app and disable auto updates.
Restart your computer for good measure then install the provided one that contains a license, if it updates, you loose the license.
