I would apply it manually, whether ot not you already have this version on your player. If it fixes the problems you’re having (particularly the green screen issue), then great. If not, call SanDisk for a warranty replacement if it is still under warranty.
And finally, get rid of that damned Sansa Updater. It’s worthless.
