Renderer only renders text

hello everybody.
i have a little problem running vvvv on netbooks. one of them is xp and the other one win7 starter.
i got to of them and on both of them vvvv is only able to render text.
as soon as i try to display a cube or any other kind of primitive/ or graphic the renderer stays black.
i runned crack on both machines and it says that everything is installed correctly.
anybody any idea?
thanks a lot

i guess this is related to Beta26 quad\renderer error on intel gma: couldn't draw vertexbuffer. E_FAIL - bug - Forum
