Always fails with convergence error

[Neptilo]

I cannot get the program to work. It runs for about a minute and then fails with a CONVERGENCE: REL_REDUCTION_OF_F_<=_FACTR*EPSMCH.
I've tried with countries "France" and "Italy", with the default values.
I tried again with those countries after updating the data from HDX (fixing the file names and the data a little bit), and then it always failed with an ABNORMAL_TERMINATION_IN_LNSRCH error.
