I started this thread and ran into a glitch tonight. I downloaded 30 designs off the Internet, unzipped them with WinZip so they all have the PES file extension, copied them to my thumb drive and inserted it into my PE 770. The machine only recognizes 1/2 of the designs. They are all for a 5 x 7 hoop, so size isn't the problem. Any ideas anyone? Also, it was a package of 30 designs from embroidery.com
