Freeframe timeblur crashes vvvv

I try to get work Petes freeframe plugin timeblur, but vvvv or my system crashes after a few minutes. I tried with several graphic cards on xp (system crashes) and vista (vvvv’s hanging). I also installed the d3dx9_30.dll for directX on vista and the bugfix for the memory problem of petes plugin:
No change. I stard to get a sort of irritated.
At the moment I work on asus notebook with vista, 2047 mb ram, 2 GHz core 2 duo, geforce go 7700
