FnaFB 1 Final Mix launch issue

I had an initial problem of loading the game, the screen would flip horizontally, and then it would crash. Fixed that problem by renaming the folder that held FnaFB 1 Final Mix the same as the .INI file. Or maybe the .exe file. They're both named the same. The game launches, rotates screen, and an error with s bunch of numbers pop up. It says "Can't convert to true integer." What do I do about this?
