Adobe Acrobat Distiller Freezing

Every time I open Adobe Acrobat, I get these two screens.  The only way I can get rid of them is to do a Force Quit of Distiller.  I can't move the top box to make any changes to the bottom box.  It's frustrating and I don't know what to do about it.  I am running MacOS Seqouia 15.3.  Please help!
