Grr

Another question from techno-illiterate me... I have a Sony Clie running Palm OS. It's decided it doesn't like Palm Reader, because when I tried to exit one ebook to the list of books, a Fatal Exception alert came up and I had to reset. I've deleted that book, as well as deleting and reinstalling Palm Reader, but it's now not opening up at all. I'm going to contact the company, but if anyone knows an easy fix (or an alternative free program that lets me read commercial ebooks), I'll love you forever...
