That is incredibly strange, I am completely unable to recreate that following the video exactly. The only other thing I can think would be if you would send a link to or post the "output_log.txt" file located in: "C:\Users\Username\AppData\LocalLow\Rising Sun Interactive\slaveRPG"
You could also try starting a new game with the quickplay option and seeing if that works, or try to use different options when creating a character.
