I guess a duration of 00:00 is problematic xD I thought I had taken that into account when I programmed it. But apparently not, I will have a look at it the days.

So I finally had time to test your session. For me it worked without problems. Nonetheless I noticed your server is very unstable and a few files were broken on the first download attempt. Thats why I added a more secure way to download the files (you can anyway check if the downloaded images and videos are all fine, after bbb-dl has downloaded them, if they are not fine, just delete the broken file and rerun bbb-dl, it will redownload missing files)

Please update by running pip install --user -U bbb-dl

If you want I can upload the video for you that I generated from your session, but I guess since it is so old you do not need it anymore.
