itch.io

I'm able to visit this page from the Itch Launcher, pretty much like any other game, but when I go to download it and add it to Library, there is an error that occurs. I'm able to download it from the website outside of the launcher, and able to extract the files via 7zip and play it that way, but I wanted it from a launcher so there is an easier access point and the game files are tucked neatly away.
