it could be that your stitching is too dense. If you resized the pattern at all, you need to check the number of stitches in original, and then in the resized to make sure the number of stitches reduced. I have a Husqvarna, and sometimes it reduces and sometimes not. If it doesn't, try reducing again. On my machine, I was told to go to "resize" first, before going to the editing screen.
