I also had 2 invalid zips (5 and 6) downloading through the SOS manager, then I tried the MAC links, which are direct download links from ‘mediafire.com’. The MAC links all worked. The MAC links are .zip files which are readable in win 7 (I assume also in Win 8 and 10).
Request: please make the SOS manager in such a way it can batch/queue download all links in stead of downloading each SOS manager executable for each part.
Thank you for this offer.
