Moved my game out of a user folder, changed the name of the folder and so on and so forth. Completely deleted the registry values in between and tried to run the bat file as an admin.
I get both random letters AND "あやかしびと". The random letters show up in the registry if I run the bat file, where as "あやかしびと" shows up by simply running the game without touching the .bat.
Here's the link to an Imgur album with pictures of all four folders in the regedit, plus a picture of my Ayakashibito folder just in case something looks wrong there: http://imgur.com/QGtX2iP,E2SU4UA,O853SmJ,lUf7EQ6,G2OZRpY#0
