It won’t open

I bought this despite the reviews because I thought that the reviewers were not too familiar with Google Docs and were not aware of how Google Docs functions, and thought their reviews were unrelated to what the App would do. Well, I am very familiar with Google Docs and should have known better that this app was not really necessary, although I will never know since it NEVER OPENED. I could nerve sign in or even use it. The Mac I have has an OS X El Capitan version 10.11.2.
