I tested all the URLs the installer uses for Aftermath: Reboot. I found that most seem to be working, but after clicking the first few, I saw a huge spike in response time. The Installer may be giving up and considering those to be timeouts. By the time I got to Visuals2.rar, I got a 502 gateway error from CloudFlare, saying the host had an error. I am thinking this is an intermittent issue with the SectorGames host. Hopefully it clears up.
