Thanks for posting all this Grr!

NOTES:
  • Music Maker seems like a nice program! However, it's ver 17 (current is 18)
  • I was unable to change the language to English.
  • There is a Language folder which contains 3 files: helpwizard_DE.ini, local_de_DE.cfg & MusicMaker_DE.dll
  • I think we'd need to find an English version and do a switch of those 3 files
