Updating Sansa without Sansa update software!

My Sansa update software does not do what it is supposed to do! Aftet I plug the little fella into usb, it doe nothing. The computer starts charging the player. Occasionally, I get an error message. The last time I tried, the player shut itself off. I couldn’t turn it on for couple days. Then, it miracelously started working. I uninstalles the updater.
Somebody here suggested that Sansa people e-mail new updates. They never responded to my e-mail.
Anybody has any idea?
