Ebook from Google Play unable to be opened in Adobe Digital Editions

Hi Everyone,

I recently bought an ebook from Google Play but I am unable to read it in Digital Editions.  I have an iMac with the latest OS if that helps.   My Network connection is fine without any problems.  I have several other ebooks that I have bought from other sites and I can read those ebooks on the Digital Editions without any trouble.  This is the first ebook that I have bought from Google Play and it doesn't work.  When I double click on the .acsm file on my desktop the following error message appears in Digital Editions:

7 Strategies for Wealth & Happiness: Power Ideas from America’s Foremost Business Philosopher:

IO Error on Network Request.

Please check your network connection and try again.

Thank you for your help in advance,
