Under your shops it has the names of both my galleries and my shop but there is an exclamation mark next to them and when I click on them I can't change the price or anything. Then when I go to my shops it says I don't have any? I've been gone a couple months. Did something change that I'm not aware of?

A lot happened. Old shops were retired, new shops were instituted to fix the coding and server lag. You'll have to create new shops. There's a whole user guide/FAQ here, a link to which can also be found on the sidebar on the News Page:
