I realise this thread was from 'quite' some time ago, but I too am coming across the same problem and I can't work out why — I've used the same file structure as before, just with updated details for the new font. Plus I tested the previous one and that all works.
I keep getting the result: makeotfexe [FATAL] not in Font Menu Name database
I've followed the notes made mentioned in the previous query. Are you able to offer any further advice?
All the best,
