I have upgraded to the Flexi19. I'm trying to do my first cut job to my USCutter MH-871. When I try to send the file to PM, I get the message "One or more panels might be invalid because the drawing extent has changed". When I click to change the file in flexi, the job shows up fine in PM but starts cutting a curve on my vinyl. If I click to not change the file in flexi, the job is not on PM. Any ideas????
