It sounds like you need to start from scratch. Make sure the stick capacity is no more than 2GB; larger ones may not be read. Put the USB stick back into the computer and reformat it for FAT or FAT 32. If it's a different format, the Bernina may not read it. Once it's formatted, copy the design back on to the stick. Then try to have the Bernina read it. It should come up on the screen immediately.
