Togainu No Chi Won't Load

Hi everyone, I installed Togainu No Chi awhile ago and started playing it. Sometime ago, I switched my region back to United States. When I switched my region and language back to Japanese, I tried to start the game but I keep getting this:

Attachment 151806

I have no idea what this says. I tried to uninstall the game and nothing would happen if I uninstalled through Control Panel. I eventually got it to uninstall by using the games installer. I then reinstalled it and ran the English patch, but the error message still shows up.

I have no idea why it's crashing since it ran previously, but if it's any help, I'm using Windows 7, thanks in advance.

Okay, I just found out my problem, I was using PowerISO and not Daemon Tools to mount the game, lock or delete this please.
