Aurora 440QE .EXP, .DST, .PES, .PEC, .JEF, .SEW, .PCS, .XXX Embroidery module with BERNINA Art Design software computer cable transfer. This is from a list of embroidery files the Aurora will read. I am wondering what the file extension is on your file you are trying to use. It is strange though this info I copied as I think back then the preferred file extension for Bernina was. ART I actually am not anywhere an expert, and I never used my Bernina 440 for embroidery, but I am thinking you need to use designs formats with some of these older file extensions. I know I cannot use some of my older embroidery designs in my newer embroidery machines. I suspect the older software cannot reformate newer files to the old extensions on the older machines.
