Imouto no Okage de Mote Sugite Yabai problems

[mamitamales]

I keep getting this when I try to open on this game.

I'm not sure what happened. I actually got all the way through Meguri's route, and then I restarted my computer, and when it turned on again, I got this message.

I had tried re-installing it. Still got this message.

My random guess would be it has to do with your system locale. Try switching to Japanese or English depending on whatever your system is currently set to.

My system locale is already in Japanese. 

It doesn't make sense that it should be in English, since it's a Japanese game...
