I downloaded a Nam model and that worked Then I wanted an HRRR model and it would not change. The Nam was shaded and would not un-shade. I am doing something wrong.

Are you talking about the great circle (Squid) downloader in Exp?
You can download multiple models at the same time. To unselect the one you don't want you should be able to click it -- when you click on a different model after that it should be unselected.
It took me a bit of time to get used to it.
