aiee that's so weird. From the code error, it really seems like one of the csv files is missing which shouldn't be a problem if your install folder looks just like the picture...
Something weird is going on... If you have Steam, maybe it could somehow work installing on there instead? Otherwise, I'm running out of ideas :/
looked at it and it does look like the photo you sent... its the legacy demo. ill try steam instead soon and hopefully that works..!
