Problem showering using Herwig++ in aMCatNLO_2.3.2.2

[antares]

Dear experts,
I am trying to run a test on showering with Herwig++. I am a CERN user and I always run everthing in lxplus. I could successfully download and install herwig++, thepeg and hepmc. During the installation of Herwig I configured it with hepmc, following some suggestions in this forum. I configured aMCatNLO to get all the right paths to all the tools.
I generated ttH events just to make a test, after having my events I try to shower them and I get this error:

Command "shower run_01" interrupted with error:
IOError : [Errno 2] No such file or directory: '/afs/cern.ch/work/m/mmantoan/submit/MG5_aMC_v2_3_2_2_matteo/tthtestshower/MCatNLO/RUN_HERWIGPP_4/events.hepmc.gz'
Please report this bug on https://bugs.launchpad.net/madgraph5
More information is found in '/afs/cern.ch/work/m/mmantoan/submit/MG5_aMC_v2_3_2_2_matteo/tthtestshower/run_01_tag_1_debug.log'.
Please attach this file to your report.

I really don't know what to do now to fix it. I put some configs here following:

What's wrong here? I seem some strange entry about lhapdf, which is configured and working.
Could you please send me help at your earliest convenience?

Thank you very much

Dear Matteo,
I'm really sorry for the incredible delay in my reply, for some reason I received notice of this
ticket only now... I assume your problem is still there. I have a few questions.

- Did you check if Herwig standalone works? For example, you can do some 'make check'
  or similar in the Herwig++ installation.

- How does your shower_card.dat look like? Are you showering with internal Herwig++
  PDFs or with the ones used for event generation? If you are showering with LHAPDF,
  could you try instead with internal PDFs?

- Could you try and add 'HepMC' and 'HepMCfio' to the environmental variable EXTRALIBS
  in the shower card? And also the path to these libraries in EXTRAPATHS.

- Could you try and see if the problem persists when using version 2.3.3?

Let me know, I'm again very sorry for this enormous delay.
Cheers.
Paolo
