Renderer (DX9) doesn't work

Hello,
I worked in the past with vvvv on Windows XP and this works fine. But now I installed vvvv on Windows 7 64 bit. I also installed .net 4, DirectX, Visual C++ 2008 and 2010. The addon pack is obviously in the vvvv folder. In the crack.exe is everything green, but my Renderer (ex9) doesn’t work. When I connect it to a Quad or a Text node, it just show me a black image.

Has anyone a clue of what the hell is going on?

Regards
Patrick

strange. do you get errors in Renderer (TTY)? what graphic card are you using? do you have latest drivers installed for it?

Ok, I’m a Idiot, I just forgot to install the graphic driver after installing windows. Now it works!

Thank you very much for this fast answer :)
