Cannot Download Households/Sims to Gallery

Problem: Cannot download to gallery (sims/households)

1. I open into online Gallery, then open into My Library, all households/lots are displayed just fine in scroll-through menu.
2. I open into any random household (no CC installed.) Family/Household photo displayed and available at all times, but right side bar with individual sim photos are unavailable or not displayed at all. (including viewing sim's traits, etc.) - Try to click on a sim's indiviual photo and this pop up error is shown. "Could not locate this item."                                                
3. anothor issue (I believe these are related): Try to click "Share household to Gallery" and pop up error is shown. "Server Error. We could not process this Gallery request. Please try again later."
4. I need step by step help to solve this. I have a Windows PC/Computer, and I'm connected to the Online Gallery just fine. (NOT offline.) Please help! Why can't I download Sims/Households to the Gallery and how do I fix it?
