Thank you, CatinaT1; I've printed out your solution for future reference.
A few days ago I solved the problem before receiving your post:
The first two successful data downloads were with my Edge browser; the third download did not come through. Just on a whim I switched to Chrome and the third download came through.
I don't understand why the first two worked with Edge, but the third required a browser change; I'm just glad to have it done.
