Ok, I am sitting with you and crying too. I just hate it when my machine has a trantrum.
Ouch, hope you can replace it and get back to the machine.
Don't fret...just use this time to download freebies or read....If you are in a shop tomorrow, they will have what you need....this is a small thing.....just be thankful the machine is not broken on the inside....or the embroidery screen when dark...that to me has to be worse, even though this is not good either....
But that exactly happen not long ago, the screen whent dark and the ligth went out too, so I slow down the speed and could finish the embroidery and took the machine to the workshoop next day and it took 3 days to fix the machine.
