Itzï is running fine here with those data.
What I did:
- Create a new location based on your map.
- create friction and rain maps:
GRASS 7.0.5 (NAD83):~ > r.mapcalc exp='n=0.004'
GRASS 7.0.5 (NAD83):~ > r.mapcalc exp='rain50=50'


  I made a new location, then re-projected the DEM map and now Itzi is
running as it should.

  Why this makes a difference I've no idea, but the simulation is running
and that's what matters.

Thanks very much for your patient help,
