Autotune 7 Crashes now

I’m not sure where to begin with this issue. I updated AT7 software just to make sure it is not AT7. Truth is, I am not sure. My process is simple:

  1. Record audio file
  2. Select the audio file
  3. Process Plugin; select AT7; Everything is ok
  4. Go to the next audio file
  5. Process Plugin; select AT7; Failure

and I get a blank window, mimicking what would have been the AT7 window size. Nuendo informs me of the error and needs to be restarted. Can anyone recreate this?
