tbh i don't use gog downloader
but i just tried to download 2 different parts from my games shelf and it it was downloading them at 45-65kb/s (not my end as my speed is 65-70mb/s)

Confirmed, https://www.gog.com/downloader/listing/alan_wake just leads to a 404 page.

i just tried to download it from my shelf, and it started downloading, op needs to contact support and see what they say :)

They also mentioned it's not an issue with the website/downloading from the library.

I believe GOG stopped supporting GOG Downloader not long before they started to push people toward using Galaxy, so even contacting them about the issue with Alan Wake's broken Downloader URL might prove a bit useless.

no i'm not using gog downloader, i meant i click on my username, go to games ,then into the search field, then alan wake, then on one of the download links and then it starts downloading that part

i can't see it being any different unless op is using a different operating system or a different web browser

I'm aware of what you're doing, I was referring to Radscorpion - their issue was with not being able to download the game through the Downloader. They wanted confirmation on whether the Downloader-specific URL for the game even worked, I replied with the confirmation that it doesn't.It is different since they prefer using the Downloader vs. methods that are known to work (like downloading through the site or GOG Galaxy).

I too can confirm that the downloader link does not work and only leads to a 404 page. I'm going to try getting it from the Backup & Goodies from GOG Galaxy.

EDIT: I can confirm that you can download it from GOG Galaxy.
