Export Errors

Hello. I am new to animate and trying to export my first scene. It's around 15 seconds long. I am unable to export as a .MOV or .swf file. When I test my movie in animate there are no issues. When I try to export as a .swf file the progress reaches 50% and crashes the whole program. When I try and export movie through AME, it comes back as an error message every time. Based on some other posts I've found, I tried exporting a simple 1-layer animation and had the same error (shown below). What am I doing wrong?
