Well, it was the weirdest thing! Finally the roads were clear enough that I could take my machine to the dealer. This was after about 3 days. I went in to pack it up, and thought, "I'd better turn this on one more time just to make sure..." and I'm so glad I did, because it went back to working perfectly! So weird! My mom thinks it reset itself after being off for a few days...I'm just glad it's working again.
I celebrated by calling my hubby and apologizing for all the whining & bellyaching I did over the situation.

Lesson learned!
