Sorry to hear you are having issues.
Fences is updated to run it's best with the current version of Windows.
You are running an old version of Windows.
Your best chance for help would be to update Windows .
Any reason why you haven't updated ?
If not going to update you can try a Purge .
Would you do this PURGE: https://forums.stardock.com/486084/fences-support-faq#reinstalling
