Lectura de ebooks en el Ipac

After several attempts of get ebooks downloaded in the IPad, the solution was, take out the app and reinstal again, authorise the IPad in the adobe account, and voila, all the books purchased got downloaded. No way to transfer the files, downloading the pdf, EPUB, or other files. Hope this helps those like me wasted time asking to the official service (where the program drives me first). 

Enjoy, keep safe
