Server Error uploading to gallery/library

Hello,

I had this happen a few times when I tried to save a house to the gallery. It just says that I cannot save to the gallery. Now it happened when I was in CAS. I couldn't save it to the gallery at all. I got this issue when I did: "Server error. We could not process this Gallery request. Please try again later."

This is a problem because I had issues trying to get out of CAS because of this. It just froze when I tried to get out of it. I had to press Ctrl + Alt + Delete  to get out of it and restart my PC.
