Prusaslicer working with Davinci 1.0

SO I just got back into using this.  I downloaded Slic3r, found a video with some settings, set it, exported some gcode, copied the gcode to the SD card, renamed it SAMPLE01.gcode, and BAM!  Successful print!  WONDERFUL I thought, I can just use Slic3r..
Except..  One of my 3d files (Well, more than 1 actually) will not slice properly on Slic3r..  I end up with sections being left blank.  Bottom line, slic3r won't work with some of the 3d files I wanna print.  So I downloaded Prusaslicer, and I can't get it to generate gcode that works on the printer.  When I tell it to print the sample, the printer freezes, and then restarts.
I have kept my printer on version 1.1.E because I do remember that one upgrade did create some issues, so I just never did one.

Any suggestions on how to get this printing again?
