First I would tripple check the threading and make sure the bobbin is in right. Try stitching a bit with the stitch regulator turned off. If you are skipping stitches with it turned off, then it's something 'mechanical' like threading, lint, needle not inserted all the way up or in a bit crooked etc. If it sews OK with the regulator off, then it may be something with the regulator itself and you might want to call the dealer for troubleshooting tips. My machine has a dial to change the stitch length in regulator mode. You can try playing with that. Does it skip only when you are going 'north and south' or 'east and west'? How does your regulator figure out your movements? mine has wheels that run on rails and if the rails are dirty the wheels can't get any traction and skip stitches.
