Answers.Body: <p>So I solved this issue by converting epub file to mobi format (mobi is the format kindle uses) and then converting back to epub. After doing this, google books didn't have issues processing it. There are multiple online converters you can use. </p>

  I converted my .epub file to .mobi using Calibre and then reconverted to .epub and uploaded to PlayBooks. IT WORKED.

  Initial things to try: Have you used an [epub validator](http://validator.idpf.org/) to confirm that it is a valid epub? Is the file encrypted in some way? (Can you view it in a browser or readium or Adobe Digital Editions)? Was the upload interrupted? I would remove and try again.
