Photo Stream not displaying on Apple TV

I uploaded a bunch of photos to my photo stream yesterday to display on my television from my Apple TV/Cloud. They looked great, but Noticed only about a half were showing. So I added more today, and now none of them are showing. I logged out from my iCloud and relogged in a few minutes later, tried to show the photo stream and it didn't work. I unplugged the unit, plugged it back in, still didn't work. I tried my family's ohoto stream instead of mine, still didn't work. And finally, I created a new photo stream, and that didn't work either.

Does any one have any suggestions as to how to make ALL (instead of half) the pictures---or at this point, any pictures---show on my iCloud photostream from my Apple TV?
