[BUG THREAD] The Sims 4 CAS Demo

I'm away, so I haven't been able to try it since Wednesday. But I had checked turned on off the internet connection, restarted my computer, downloaded sums from the community and tried to reupload them, remake and try to upload, and as of Wed. night nothing worked. I still received the same message. It only worked for half my play session on the first day I had the demo. What do you suggest I try?
