[Emcee]

Hi all - I am Emcee - a newbie to this group. I am using Calibre and for some reason I am unable to convert my files to EPUB so they can be read. I can convert to MOBI but my sony reader is not too fond of MOBI. The problem with the conversion is all the lines run together - squished like - I get about 15 lines in one half inch - hard to explain - but a 150 page book is reduced down to about 30 pages if you get my drift. I am not too technically challenged but I really don't know how to go about fixing this problem. This problem helps whether I am converting from LIT or MOBI to EPUB. I haven't tried any other formats
Thanks for helping
