It's like the problem I keep getting when users have a new computer.
Why isn't there anything in my Recently Opened Files list?*
Because you haven't yet recently opened any files yet. Once you have opened a file, then you will have recently opened a file, until you have opened a file, you haven't yet recently opened any files.
*Actually, they rarely proffer the problem that way. It's usually: I can't find my files! Well, where did you save them? I don't know, they used to just turn up when I wanted them.
