    Hi Hatari Labs, I ran into a problem when the pictures of sentinel 2 appear in the list, but it is impossible to preview or save in layers for further work, Error 40. How can I fix this?

    This is wrong, once you have downloaded the sentinal 2 data, and prieview the image,, click the top icon next to the preview box (top right) and it will show as a low resolution image on you workspace. Once you checked that, it wll only download images shown in your workspace....
