I don't have a Bernina but I have dreamed of getting one. The computer is what I don't want to have to deal with. If I cannot tinker with it myself, I will not get it. I know I cannot afford to visit the repairer as often as I probably will have to.
I've been hearing a lot lately about Bernina's being problem children. I'm sorry. Stick with it. Someone has probably had the same issue you did. Hopefully, Bernina Jeff will be able to offer solutions for any unique problems. I bet if you asked here in the QB, there may be other Bernina fans that can help.
