Vvvv 29.2 crash

hi…

when i start vvvv 29.2 the screenshot appeare but not the empty patch and when i click on the vvvv window, win close me the vvvv application.

the non-sense thing is that:

  1. i have normaly used vvvv 29.2 until one week a go, and from one moment to an other vvvv is no longer started .i have not install anything in tis time.
  2. i have on the pc three version of vvvv: 27.1, 28, 29.2 and now only the 27.1 go.

idea or anything else to solve this problem?
