Whenever I try to run it through steam I get error code 51
Searched around and this is a networking/firewall problem, but adding steam and amnesia as exceptions didn't work.
Anyone had this problem or have any understanding of how to fix it?
I'm using Avast

You might have already read this, but it will be of good reference. It seems 51 can be caused by interfering background programs, so try to shut down a few. Perhaps a hidden process is causing it in this case.
