[Users] Some questions about new release 2013_05

1) I just tried to run some of my "old" parameter files using the new ET
release and I got some strange results. The parameter files which work
completely fine for previous releases do not work anymore in a sense that
for example for the binary neutron star simulations starting from LORENE
initial data hamiltonian constraint blows up and central density become nan
shortly after the beginning. Thus, I have a question are there any
essential changes I need to incorporate in my par files due to the new
release or the old par files should in principle work and give same results
as before?

2) I'm trying to use ML_CCZ4 for the spacetime evolution  and I found the
example par file for BBH evolution in McLachlan/par/CCZ4/bbh_ccz4.par which
does not work. I figured that this file was for the old implementation of
the ccz4 inside ML_BSSN thorn and if I replace ML_BSSN with ML_CCZ4 and
comment some of the parameters it works. However, I was wondering if you
could provide a working example of such a file with ML_CCZ4?

Thank you.
