Well, I've found the keystrokes as mentioned. One site indicated a dialogue box would appear to reset and another said, you don't see anything and it just happens.
Meanwhile, I had stumbled in the preferences button that shows them in explorer. So I deleted all of the files that showed moments ago and when I restart, it creates a new set.
Is that considered a reset? I dont know.
None if this works however. Nothing from today will open or import in to a new project.
Somehow in renders using AME, some were saved from two days ago and they import in.
That's helpful but I'd really like to figure this out.
