Heal the "Photos" live tile in Windows 8 when it gets sickly.

Well this worked for me:

• Go to: Control Panel > All Control Panel Items > Personalization (or right-click in open space on the desktop and pick "Personalization")
• At the dialog box which appears go to: View > Refresh

 
 

...by "sickly" I mean that it would not display my photos.

Addendum 5/7/2014: I think you may need to select the current theme and then pick the refresh option. I keep needing to do this. I think something in my startup makes the photo tile sick.
