Revisiting this thread, currently stumped. So, after following your advice, it failing to load, then re-installing the game, I encountered the same issues. I actually get a similar message when trying to open the game through Steam or utilizing the shortcut, except it specifies the .exe for Microvolts instead of the other file.
Once I open it through the .exe, with administrator privileges on both Steam and the .exe itself, I receive the -exact- same error code as listed at the start of the thread.
Maybe this is a permissions issue / communication with Windows Firewall? I'll run some tests.
(Small Edit: The file was the same, one string of code was different. 0023:7B7CB0E9)
