Re-Did Firmware

I was a little upset that my sansa e250 stopped playing my iMesh subscription music. I connect it every 2-3 days so it’s always update. My subscription fees are auto paid by my credit card which always has room on it. I tried re-installing WMP11 and still nothing. I had to re do and or update the firmware and finally it’s working again. Stupid, but that’s tech gadgets eh?
