Hello, I'm Tom. I already extract the file game and when i open the file inside it, show two files "Grisaia.mdf" and "Grisaia.mds". When i tried to open it, it said that i need a program to open it. So i tried to install the "Grisaia_no_Kajitsu_English_1.1" application but it said that "The folder you selected does not appeared to have a valid version of the game installed. Please double check you've selected the folder and try again. Did i do something wrong? Thank you
