I purchased my bernina 440 qe with embroidery unit about 12 months ago. I have attended several classes and there seems to be a learning curve for individuals and dealers alike. The demonstrators had trouble getting the embroidery software to work with different computers, there was a difference of opinion between experts if a dongle was required or not, and whether or not it was necessary to purchase the expensive software or not. So, I have to say, I have been left feeling quite confused myself regarding my embroidery software. I was really excited when my dealers found an expert on my machine and called us all back in. She offered to have asleep over so that we could all get more comfortable. I am using my unit, but still confused about upgrading software options,what comes with software upgrade and how will it change my embroidery experience, will any embroidery CD work with my unit?? I have only an old singer to compare my bernina 440 qe and embroidery unit to, and will say there is no comparison. Prior to my bernina, I sewed only when necessary
