Litchi not downloading and stitching panos?

I can successfully do a world pano (looking down, and all around), and at the end of it, Litchi seems to download (at least) the low-res version of the shots…but when I do land, and leave the controller, iPhone and Mac Pro 2 on, it will not download and create any resolution spherical pano (like I used to have it do) - not in high, medium or low resolutions…ideas? The photos are definitely on the card…
