TopSpiiiiiin: Well, RIP 194 games, I guess...
JMich: Use GOG Downloader or Galaxy (or lgogdownloader, or gogrepo.py) and you should be able to download your games just fine.
Also check if any browser scripts are interfering.
I have tried multiple browsers (Edge, Firefox, Chromium) with and without extensions and even multiple OS' (Debian, W10, W7). The GOG Downloader doesn't work, but Galaxy does, with slow and heavily fluctuating speeds, better than nothing for now, I guess. Anyway, thank you, I hope the problem doesn't persist. :)
