Unable to open app store
I have a 2014 MacBook Pro operating on El Capitan 10.11.1. For about a week now I have been unable to open the App Store. Any time I click on it, the icon just bounces but nothing happens. I have tried force quitting, and re opening but the same thing happens. I have signed out of iTunes with no change. I am not sure where to go from here. Thanks for any help.
MacBook Pro with Retina display, OS X El Capitan (10.11.1)
