I have the same machine and Love, love love the embroidery!
The machine can use ART and PES files, I use them both all the time. Occasionally the colors on the PES are wacky, but you tend to use your own colors anyway. There are tons of free designs out there. There are also clubs you can pay to join that give you a number of new designs each month. My favorite is the Silver Threads Golden Needles club with OPW (Oregon Patchworks). One site has 1 free design each hour, 1 free hunt each hour and 1 free design each day. They also have dollar hour where a certain page of designs is $1 and every once in a while you can catch Happy Hour, where all designs are 50% off (usually $4)the site is

If you google free machine embroidery designs you will be pleased with all that you find. The Bernina website has some freebies also. Trust me it is almost as addictive as collecting fabric!
You can download the files to your laptop with no problem. If you have a problem, PM me and maybe we can chat.
I think that your Bernina dealer should offer classes also...I learned a lot there. OH, did your embroidery module come with Editor Lite software or Art Design? Doesn't change a lot, but you have to have a security dongle with the Editor lite.
Oh, there is a Yahoo 440QE and embroidery board.
