Google Docs Not Responding

[MOLITTLE]

I am using a Lenovo Yoga 2 tablet running ANDROID operating System. I created some documents earlier but now when I select GOOGLE DOCS I just get a white page with the Google Docs App symbol on it. If I press it says NOT RESPONDING and gives options Wait, Report or o.k. I tried clearing cache uninstalling and reinstalling the app but no change. If I press the Google Drive app the documents are shown in there. help please.
