"THC Enabled" not activated

Hi, as cutting some steel without THC, I unticked the THC ENABLED in the material cut parameter. But afterwards, I ticked THC ENABLED to use it again, the THC enabled light will not go back to green again(in the auto and enabled mode as seen in the attached picture). I tried to enable the pin plasmac.thc-enabled but plasmac says the pin could not be changed. Is there any way to resolve the issue or I need to reintall plasmac again. Thanks.

I reinstalled and everything works fine now! Thanks.

Sorry but I thought I replied...
Glad you got it going.
