I can't run Harvest Moon Magical Melody

[lucascg]

Ok, nothing works for me. With the Open GL plugin, I only get the sound and 7 FPS, but a blank image. With the Direct 3D9, I get the sound ok, 30 FPS but the image keeps flashing green. I have Dual Core enabled and Idle Skipping disabled. My specs are

Vista 64bits
4GB RAM
GeForce 9800GTX
Core 2 Duo 2.8Ghz

Help?
