Issue with WHIZARD 3.0.3

Hi,
I'm not an expert in WHIZARD. I'm using with version 3.03 a sindarin input file I was using time ago with version 2.8.2 to generate mu+mu-->H nunu at 3 TeV center of mass energy. I guess I have to change something, but I was not able to find that in the manual and/or notes.
Thanks for any help you can give.

process hdec = "e2", "E2" => "H", NNU, ANU
process hbb = "H" => q, qbar

integrate (hbb)
unstable "H" (hbb)
integrate (hdec)

After the integration that seems OK, I get this message:
