Hi-just bought a used brother PE780-d and love what I've been able to do with it-so far, only the designs that came with the machine. I purchased a monogram alphabet and after weeks of figuring out how to unzip , etc., I finally created a three letter monogram! It was working on my machine (the monogram was stitching out perfectly!), but the bobbin thread ran out, so i changed that. Then the needle broke, and i fixed that after 3 in a row broke. Now, for some reason, I can't get the usb to display the pattern on the machine. I deleted the file from the usb and tried starting all over. i have followed all directions, but can't get it to work-getting very frustrated!! Any ideas whats happened??
