Human Cell Atlas Matrix Downloader database problem

When trying to use HCA Downloader, it outputs an error "the project identifier XXX was not found in the database" even though I tried using subsequently project title, project label and project UUID - all failed. It happened for three different projects I tried but when I tested the project that is given as an example ("Single cell transcriptome analysis of human pancreas"), it worked with this one only.

Another problem with this tool that I encountered was when I tested "Species to use" box, using "Single cell transcriptome analysis of human pancreas" project (because only this seemed to work). I typed "Homo sapiens" as HCA Atlas indicates, and this time the tool failed, with an error:
`usage: Download data via HCA DCP FTP. Requires -p input. Files are downloaded into current working directory.
[-h] -p PROJECT [-f {loom,mtx}] [-o OUTPREFIX] [-s SPECIES]
Download data via HCA DCP FTP. Requires -p input. Files are downloaded into current working directory.: error: unrecognized arguments: sapiens`

Here is the history with all those datasets: https://usegalaxy.eu/u/j.jakiela/h/hca-data
