Help with 2.7

I had Scrivener open today and was working on a project, when I got the pop-up to upgrade and relaunch. I did, but now I can’t do anything with Scrivener.

The icon looks like this: I am able to open Scrivener, but that’s all I can do. I can’t open any files, and I can’t quit it, have to force quit it.

I’m using a Macbook Pro, running Yosemite. I’ve restarted, thinking that might help, but nothing. Any advice/suggestions?

What if you redownload the app again and reinstall?
