Acrobat Distiller won't start

Hello, snce I have a newer imac with Mojave, my distiller won't start up; I really need my distiller for making PDF. I uninstalled Acrobat DC, installed the latest version and updated it (see picture) but still nothing. The strange thing is that it worked normally last week. But since yesterday it won't start??? Can you please help me??? I sent many reports already.
