EA app not launching

So, I downloaded the EA app on my Mac in february which is when I got this Mac and the icon was grey and had a line over it. Now when I try to launch the EA app on it's own it just says that I can't launch it because it might be damaged or incomplete. 

I tried redownloading the app and deleting the "damaged" one, but when I try to delete it, it just says the operation can't be completed because it needs to be downloaded.

I still can play The Sims however and that way the app does launch. I don't know if this is something I did wrong or if it's a serious issue but I need help anyways since this is driving me nuts and I am fuming.
