Welcome to MR, Bob
I just checked out your site and wasn't able to see where you listed the formats available for purchase of your book. I was directed to pay pal when I clicked.
What formats are available? Epub is one that is used across a wide variety of devices. We are an international forum and love to support authors who participate in our discussions.
Also, supplying additional information about the problem you are having with the text of your book will give members a better idea of how to help. For example, the format you downloaded, etc.
