I'm having some problems with my Kobo. I had a friend put a whole load of box into a Dropbox file. Downloaded everything fine, created a folder, alphabetized it all but when I downloaded a book to test everything came up as so much gibberish. This is not a font size problem, most of the text doesn't make any sense. Now I know Umberto Eco is a difficult author, but this is crazy

Anyone know of a fix? Like I said the text is legible but all of the letters just seem to be scrambled on the page.
