I am new to android and tablets. Got my wife a digix 10" tab for christmas. The Kindle app was working and I managed to download 2 books. with the Kindle app you could read the books. My wife attempted to down load another book, Now when we touch the kindle app it goes to amazon.com/kindle books. Amazon said delete the app and redownload.so I made the app inactive and downloaded the app fromm play store. Can't find it. it is probably inactive also. how do I delete it and download new. When downloaded does the app show up on the home screen or do I need to do something else? Sorry if this is a dumb question but I am trying to learn before My wife gets discouraged with the tablet. the tablet has the ice cream sandwich OS.Thanks for any help.
