Support gave a link to older version I tried all their suggestions and even though the calendar worked after dragging a camera to the center then drag the center back to where the camera was, I found after doing that the live view did not display then. So back to 8.8.5 version.
Here is the link if you are also unsuccessful with 8.10.4
