Any thoughts about what could be happening?
I would expect that when you open the emailed version you are not seeing the message bar at the top of the db window that says the db is protected and read only. This happens because it came from somewhere else as a download. I'm not surprised that you cannot open an emailed db with your version of Windows and Access.
