My PPD wont run on Windows 7?

Hello... you see I have this issue.
I've been trying to get PPD for quite some time now.. about a month but I can never
figure out what is the problem.
I have songs, Direct X, and all of the other nessascary things for the game but for some reason
I will log in and all I see is a dark black screen. I know other people have been having this problem too and I
know people just say "get an old version of ppd" and yes I know that but It still wont work even if I use an older version.

I also can't open Key Configer either...

I'm this close to sticking to Project Diva pc.. and that sim isn't as good as yours...

Someone please help me!
