Winterborn: ....& would be grateful if anyone can help.

I installed Giana Sisters on my computer, it flicks to full screen when I try to load it in Direct X 9 mode and then says direct x has crashed and closes the application. I tried in 10/11 mode but then it wouldn't start at all.

I tried to install Directx 9.0c but it won't let me as I have 11 on my computer already

I tried uninstalling and re-installing but it hasn't helped either. Any ideas on how to make the game run?

When I install the update I get a fatal error when loading the launcher and when trying to start the game on either mode.
"failed to load a shader for particle type0"
