Hello,
Please try purge and reinstall steps as mention here : [Link]. Do the purge as mention in the guide, re download the latest version that available to you from your account page. Reboot after the purge. Reinstall and reboot again after the installation. Retest and report back here.
Your saved layout snapshots should still be there after the purge, but if you worried you can use this guide to backup your layout snapshot: https://forums.stardock.com/486084/fences-support-faq#backupsnapshots
Thank you,
