Please let us know what version of Fences you are using?
For your info, I am running 3.0.9.11.
If you also running the same version please do the purge and reinstall steps : https://forums.stardock.com/486084/fences-support-faq#reinstalling
Please re-download the latest version from your account in Stardock and install that version. And reboot after that. And check if it working.
And report back.
Thank you,
