[Harden Taylor]

HELP! Although I should probably know better seeing as how I predate the invention of dirt, I've fallen into the bad habit of writing ebooks (novels and a short story collection). Smashwords.com has accepted four of my novels in the premium catalog but indicates that two will not be accepted by Apple because of epub errors. The message I get from the automated checking device recommended by Smashwords.com states, "No epub file to check was specified in arguments." I have no clue as to what this means. I've followed all the formatting rules, performed the "nuclear option" twice (don't worry, I'm not a terrorist though I feel terrorized by this process) and have requested help but received no response. Is there a kind-hearted nerd out there somewhere who would be willing to help me? I should point out that one of the self-help options mentioned was to try the Mobileread Forums so I think I'm not too far out of line requesting help here though I may be in the wrong forum (I'm still struggling to get out of the 19th century and into the 20th, thus my ignorance of things modern).
Best Regards, Harden Taylor
