I have the Filemate Identity tablet. I can go to my county library and loan ebooks on my account. Once I have the ebook loan, I need to download it. It's format is .epub and my tablet says it cannot download that type. Is there a way to be able to download ebooks from the library? This is the reason I got the tablet. I don't want to go to the app store and buy books. Help! Otherwise I want to see it.
