I have a Bernina 440 and also Bernina Designer Plus software ver. 6. Did you take the classes for your machine when you bought it? I bought mine used and was able to pay my local dealer an "adoption fee" that included all the classes plus servicing for a year. I learned a lot from the classes. If you didn't take the classes, you can download the workbook and do the exercises to help you become more famillar with the functions. My dealer has the wookbooks posted online:

I really get a lot of information from two different Yahoo groups:
