When I open Lightroom CC it will not let me add photos.

I'm working on a Mac with the most recent type of Lightroom CC and I have never used Lightroom CC before on this specific computer. I just recently downloaded the app with my subscription and when I open the application and go to the plus icon in the top left icon it doesn't give me the option to add new photos. I can keep clicking the icon but nothing happens, the icon doesn't even illuminate. I've searched through numerous threads and forums for an answer but nothing is helping. I have even tried unistalling and reinstalling the app twice and still no luck. I would assume based off the fact that Adobe is a well respected company and I have used their products numerous times that there should be a reasonable solution to this issue. If someone could try to point that solution out to me as fast as possible that would be great. Thank you in advance.
