Question NZXT H500I Case lights not working

[Aphrica]

I built my PC around a week ago and its been working fine but about 2 days ago the led lights stopped working. They are not getting detected by CAM.

Pc on: reinstall Cam
Pc off: unplug strips.
Reboot. Run Cam
Shutdown. Plug in strips
Reboot. Run Cam.

Just had a Windows update, it can mess with some software, over-riding permissions previously established or changing drivers
