Problem running EarthImpact example

[SPopov6]

I was trying to run the example code for EarthImpact, and this error has come up:

[00000.0] ic_info_read_hdf5: Metadata group ICs_parameters not found in ICs file [00000.1] single_io.c:read_array_single():101: Compulsory data set 'SmoothingLength' not present in the file.

Is there something missing or wrong with the initial conditions file?
