It's asking me for a serial key. When I open startup.exe, it comes with a serial key with 20 characters, which doesn't seem to fit the 16 character license code for the game.
It works now. You have to right click on the title screen to open the game's settings. The game's audio is muted by default. And I'm used to open VNs' settings on the title screen.
I know what it says, you don't need to be mean. I'm just not very tech-savy to solve this problem on my own.
Also, I'm only paying it because I want to get a recording of the ending song.
Ok, I think it works fine now. But there is no audio. What's up with that. There's a file called IMAADP32.ACM inside the "patch problems audio", but what do I do with it?
