[gmx-users] Gromacs version for polarizable model

Dear all,
I am trying to use a polarizable model for acetone molecule. After
lots of attempts we created a stable model for a single acetone
molecule in a sea of water running the simulation on one core.
So then we started new simulations with a certain number of acetone
molecules and the simulation appeared to run, but unfortunately it
doesn't write anything in log file, xtc or trr files.

Is this a problema connected with an old version of the code (4.5.4)
that I used?
If yes, which code should I get?

In thw following lines I show:
