Wait! Hold everything!
I assumed (silly me!) that you knew the stylus is special. It is far more than a piece of plastic. (See excellent posts by Gunner on this point.) Any old thing will work on the tablet side. Not so for the e-ink side. There is probably nothing wrong with your PE at all. If you can't find your stylus, search this forum for what and where to buy.
Good luck! Enjoy!
