I expect that your case.inst file is not suitable. Try
instgen_lapw (and overwrite the old one). Did it say it finds 64 atoms ?
With the new case.inst file run x lstart and (if there is no problem
reported in case.outputst) x dstart (-c)

Do NOT mess around with these parameters. Usually you MUST NOT change
parameters except NMATMAX and NUME, unless you "know what you are doing".
