Make sure that you don't have a space before or after the password (happens quickly when copy/pasting). I'll add a couple of mirrors and replace the episode with a single link soon though.
Hello,Ryzen.I extracted the downloaded RAR files (part1–part6) using 7-Zip. However, I get an error with Voice.xp3. The game itself launches, but there's no voice audio. I apologize for the trouble, but I'd really appreciate it if you could look into this issue.
