Vvvv crashes at splash screen

hi, trying to get vvvv to run on a windows7 64bit machine. ive installed dx9rd and .net4. vvvv launches, displays splash screen and freezes.
i’ve tried compatibility mode (xpsp2).

any ideas?
thx

what does starting crack.exe tell you?

.net4 guided to something bad with beta21 i think… was long time ago

crack says,
DX 9c june 2010 is installed
.Net 3.5 SP1 is installed

AddFlow Active-X tick
DirectShow filter tick
File type association tick

try switch everything off in crack, and then ON
