At first: Sorry for my english.
Yesterday I tried to download the game Togainu No Chi. So far so good...
I already have the System locale on JP. I also downloaded the game and the english patch and also DAEMON or so.
But the game doesn't start...it says, I don't have the DirectX Version I Need for the game. I know that I Need the DirectX Version 9.0 (I guess). I have the Version DirectX 11, so I tried to install the DriectX Version 9.0, but this doesn't work! I don't know why...it says that I Need Windows 98, Windows Millenium Edition, Wndows 2000, Windows XP or Windows Server 2003...My Laptop has Windows 8.1.

I don't know what to do

I also can't upgrade the game. I don't know why, the text in the Information is in japanese...

Please! I want to Play this game
