1. I was working on site a (the one that is now gone).
2. I had a client call for an update on another site. (site b)
3. in RSD, I went to the file menu (while site a was open in rsd) and selected site b from the recent file menu.
4. RSD asked me to save like it always does before opening site b.
5. Updated site b and closed out the whole program.
6. Today, I go to work on site a and it is now site b that comes up!
How is this possible? And, is there ANYTHING I can do to recover site a????
