hi nbfsinger.welcome to the forums (in boris' behalf)

i don't have an answer to the epub issue since I have not encountered that but if you are just interested in having a Bible in your edge, try downloading the one in mobileread. it is epub but it seems to work fine.

if you need a solution to the particular file try contracting tech support by email and send them that particular file so they can try to reproduce the problem and hopefully give you a solution.
