My brother gave me the Bundle for Racial Justice as a gift and I downloaded the .dmg for my Mac. At the start of the install I am getting the following 404 error. Attached screenshot. 

I'm having the exact same error on windows

I read some other threads and i believe this issue is caused by the influx of people on itch servers right now, they suggested to just wait until less people are on it.

Thanks for replying. I got a reply from you before I got one from itch.io customer service.
