I had a problem downloading a book.
I don't know if it is a problem with the computar I am using, but I was trying to download a free E-book that was in ePub format and I don't know what to open it with, I cannot open it with Adobe Reader, which is obviously the default for my computar because it would not let me chose other programs to open it with, I need help resolving that issue.
