kodi add on couldn’t be loaded

Hi
Today I installed a Hauppage WinTV driver update.
When I launched the TV module I get an error message ‘ add on couldn’t be loaded’ and ‘ PVR manager is starting up’ ( stuck at 0%). I rolled driver back, but now keep getting this error.
Went to add ons’ to try and uninstall and reinstall next PVR add on, but no uninstall option. It’s greyed out. How can I reset ? Any help appreciated. Ps. next PVR works fine on its own. Thanks
