Thanks to Cheryl in Oz, whose dealer demonstrated her new 440 for her before she took it home. She told me to try turning the machine off and pushing in the button before installing the BSR and turning it on. I did it and the button actually went in and stayed in. I installed the BSR and it works beautifully. I did a little sample with curves and loops and feathers and it looks so nice.
What a relief! I don't have to take the machine back to the dealer on Tuesday!!!! RCTQers are the best. :)
