When I upgraded my Pfaff I had a few threading problems because I was doing it the way I did with my previous Pfaffs. After blaming the machine it finally dawned on me to take out the manual. I slowly step by step and that made me see where I went wrong.
If that doesn't work for you I'd go back to the dealer with the machine and have them try to solve the problems.
