How to fix a consistently freezing app download? On my new Motorola X, I am downloading an app (Amazon's Kindle app) from the Google Play store and it is consistently getting to 91% downloading and then freezing there. 

I can cancel the download and try it again, but it always stops at 91%.

Is there a way to reset the download so it truly starts from scratch? Or is there something else I should try?
Ok this happens to me all the time I just go to app settings and then go to google play and them force stop and there it works
