after the battery died, i replaced it with the SAME battery, and the scale still didn't work. i tapped the corner, followed directions, EVERYTHING. I already went thru this with one of these scales. i thought it was disfunctional and threw it away and went and bought another of the same. this one is doing the SAME thing. i love the scale, it works great, up until the battery dies, and when i replace it...it doesn't work. what do i do?
